Amazing Illusion - Squares Are The Same Colour!



This new illusion has been making the rounds of the Internet the last few days:



What's the illusion? It's that the two squares are actually the same colour, it's just the edges that are different. The middle area, where these edges meet, causes the illusion. When covered up you can see the two upper and lower sections are the same colour. Try put your pinky over the middle are where the squares meet:


It's actually just a take on the well-known Cornsweet illusion, which takes advantage of a phenomenon that occurs in your brain called lateral inhibition.
To understand how it works, you first need to know a little about how we see things. Cells on the back walls of our eyes react to the energy in light that is funneled to them.
They get excited and send an electric impulse to special cells in the brain, which collate signals from many eye cells and send the average of those signals on.
These brain cells interpret the millions of signals coming from the millions of eye cells into a picture with brightness and different colours.
There are special ways that these brain cells influence each other. Lateral inhibition is one of those interactions — the more active brain cell tones down the sensitivity of the one next to it, making it less excited.
That amplifies the signal on one side of the black/white boundary and diminishes the signal on the other side of the boundary, creating more contrast between them than actually exists. It allows us to see more vividly, but also creates these optical illusions.
It is also active in our other senses, like hearing, touching, and smelling.
Here are some more examples:
The Grey Square or Checker Shadow Illusion. The squares A and B are the same colour:

And here's a gif proving it:



There's also the Grid Illusion, which produces grey dots at the intersections of these white bars:

I hope you have enjoyed these awesome optical illusions. Check out some of the cool links below if you want to see more:

What Nothingness Feels Like – Inside a Sensory Deprivation Tank

If you haven’t experienced one of these, YOU MUST. It is life-changing. Period. The level of relaxation is unprecedented and it allows your mind to go places it never has before. It feels like pure awareness floating in space. Like a dream. There is nothing that I have felt that comes close. The only comparable thing could be a complete anti-gravity chamber in pitch black.



One of the greatest tools ever for exploring your mind . . .What do you think? Will you try it?

Here is an interesting blog from someone who experienced the tank for himself :

9 Drawings Done By An Artist Under The Influence Of LSD


These 9 drawings were done by an artist under the influence of LSD — part of a test conducted by the US government during it’s dalliance with psychotomimetic drugs in the late 1950′s. The artist was given a dose of LSD 25 and free access to an activity box full of crayons and pencils. His subject is the medico that jabbed him.


First drawing is done 20 minutes after the first dose (50ug)


An attending doctor observes - Patient chooses to start drawing with charcoal. The subject of the experiment reports - 'Condition normal... no effect from the drug yet'.

85 minutes after first dose and 20 minutes after a second dose has been administered (50ug + 50ug)


The patient seems euphoric. 'I can see you clearly, so clearly. This... you... it's all ... I'm having a little trouble controlling this pencil. It seems to want to keep going.'


2 hours 30 minutes after first dose.


Patient appears very focus on the business of drawing. 'Outlines seem normal, but very vivid - everything is changing colour. My hand must follow the bold sweep of the lines. I feel as if my consciousness is situated in the part of my body that's now active - my hand, my elbow... my tongue'.

2 hours 32 minutes after first dose.


Patient seems gripped by his pad of paper. 'I'm trying another drawing. The outlines of the model are normal, but now those of my drawing are not. The outline of my hand is going weird too. It's not a very good drawing is it? I give up - I'll try again...'

2 hours 35 minutes after first dose.


Patient follows quickly with another drawing. 'I'll do a drawing in one flourish... without stopping... one line, no break!' Upon completing the drawing the patient starts laughing, then becomes startled by something on the floor.

2 hours 45 minutes after first dose.


Patient tries to climb into activity box, and is generally agitated - responds slowly to the suggestion he might like to draw some more. He has become largely none verbal. 'I am... everything is... changed... they're calling... your face... interwoven... who is...' Patient mumbles inaudibly to a tune (sounds like 'Thanks for the memory). He changes medium to Tempera.

4 hours 25 minutes after first dose.


Patient retreated to the bunk, spending approximately 2 hours lying, waving his hands in the air. His return to the activity box is sudden and deliberate, changing media to pen and water colour. 'This will be the best drawing, Like the first one, only better. If I'm not careful I'll lose control of my movements, but I won't, because I know. I know' - (this saying is then repeated many times). Patient makes the last half-a-dozen strokes of the drawing while running back and forth across the room.

5 hours 45 minutes after first dose.


Patient continues to move about the room, intersecting the space in complex variations. It's an hour and a half before he settles down to draw again - he appears over the effects of the drug. 'I can feel my knees again, I think it's starting to wear off. This is a pretty good drawing - this pencil is mighty hard to hold' - (he is holding a crayon).

8 hours after first dose.


Patient sits on bunk bed. He reports the intoxication has worn off except for the occasional distorting of our faces. We ask for a final drawing which he performs with little enthusiasm. 'I have nothing to say about this last drawing, it is bad and uninteresting, I want to go home now.'




10 Ways to Become More Conscious



What does it mean to become more conscious?  It is the progressive realization of conscious mastery over your mind.
The challenge is that it takes consciousness to grow consciousness.  But you needn’t worry about this because you already have the seed.  Think of it like fire.  You have a flame, and you want to turn that flame into a huge blaze.  How do you do it?  You add fuel.  The following list includes examples of how you can add fuel to your flame of consciousness to become a raging inferno of consciousness.  Well, OK, the analogy sort of falls apart there, but you get the idea.
So here are 10 ways to raise your consciousness:
1. Truth
Truth raises your consciousness.  Falsehood lowers it.
First, accept the truth.  Whatever you’re afraid to know lowers your consciousness.  Step on the scale to see how much you weigh.  Have a long talk with your spouse about the status of your relationship.  Take a deep look at your career.  In every case accept the outcome.  Don’t just acknowledge the current status and dismiss it.  Really accept it as the truth.  Think about what it means for this to be true.  Also accept your feelings about the truth, whether you like them or not.
Secondly, speak the truth.  If honesty is a challenge for you, it’s because you aren’t being honest enough with yourself.  Lies you tell others are shadowed by lies you tell yourself.  Take note of those areas where you feel incapable of genuine honesty, and dig deep enough to find out why.  You’ll find that you uncover a part of yourself you’ve been unwilling to accept.  You don’t lie about the parts of yourself you accept 100%.
The more you’re able to accept and speak the truth, the more conscious you become.  Raise your consciousness by uncovering and dumping all traces of falsehood from your life.  Allow this to be a gradual process.  As your consciousness increases, genuine honesty will come more easily to you.
Yes, there may be consequences when you switch from lies and half-truths to the full truth, but highly conscious people know that crossing that bridge is well worth the effect.  A short-term adjustment is nothing compared to the joys of living honestly and openly.  It’s so much easier and less stressful to be yourself and allow others to do the same.  Not everyone will appreciate the real you, especially if they’ve grown accustomed to a false version, but that won’t matter once you accept and appreciate yourself.
2. Courage
Courage raises your consciousness.  Cowardice lowers it.
Courage is the gatekeeper between unconscious growth and conscious growth.  As long as you remain on the unconscious side, life will keep throwing problems at you until you step up and take charge.  When you face your fear, the fear vanishes, and problems transform into opportunities.  But when you run from your problems, your fear only grows.
A powerful guiding principle to adopt is, “Whatever I fear, I must face.”  The more fears you face down, the more conscious you become.  As you master this lesson, eventually courage becomes less necessary.  Once you develop the courage to face any fear life throws at you, you stop attracting so many fear-based experiences into your life.  This is why courage is the dividing line between unconscious growth and conscious growth.  The mastery of courage gives you the power to decide how you’ll grow instead of being a victim of the whims of fate.
3. Compassion
Compassion raises your consciousness.  Cruelty lowers it.
A great way to become more conscious is to search for signs of unconscious cruelty and disconnection in your life.  This can be very difficult to do since it also requires courage.  We naturally resist facing our own cruelty, but it’s there just waiting to be uncovered.
Compassion is the root of unconditional love, a feeling of connectedness with everything that exists.  Do you feel connected to yourself?  To others?  To animals?  To all living things?  To everything that exists?  The more you develop this connection, the more conscious and aware you become.
4. Desire
Desire raises your consciousness.  Apathy lowers it.
When you get clear about what you want, such as by setting a goal, you raise your consciousness.  Clarity focuses your mind and gives you the power to think and act intelligently.  You can feel this effect whenever you think about something you definitely want.
On the other hand, when your desire is unclear, your consciousness is muddled.  Your thoughts lack focus and direction, and you merely spin your wheels.
Strive to become more clear about what you truly desire most, and your consciousness will expand.
5. Attention
Attention raises your consciousness.  Distraction lowers it.
Improving your ability to concentrate will make you more conscious.  Pick up a rock and give it your full and complete attention, and notice what happens.
But allow your mind to be riddled with distractions, and your consciousness will sink.  A distracted mind is a powerless mind.
Meditation is a great way to practice attention and concentration.  Sit quietly, breathe deeply, and focus your mind as you do your best to tune out distracting thoughts.  This is simple to learn, but it can take a lifetime to master.
6. Knowledge
Knowledge raises your consciousness.  Ignorance lowers it.
First and foremost, know thyself.  Think deeply about your life, and keep a journal to record your thoughts.  Ask questions to which you don’t know the answer, and then search for those answers.
Look around you as well, and soak up knowledge like a sponge.  Interact with your environment with a sense of curiosity and wonder.  Study it.  Learn from it.  Experiment with it.
Strive to understand reality, including your role in it, as accurately as possible.  The more accurate your beliefs about reality are, the more conscious you become.
7. Reason
Reason raises your consciousness.  Irrationality lowers it.
Logic is a powerful tool of consciousness when used correctly.  It lends structure and substance to thought.
However, the great challenge of logic is the avoidance of false assumptions.  A single false assumption can throw off a lifetime of otherwise logical conclusions.  So challenge all of your beliefs, and never have too much certainty about those that rest on clouds.
8. Conscious people
Conscious people raise your consciousness.  Unconscious people lower it.
Seek out others you perceive to be at a higher level of consciousness than you are.  Talk to them, ask questions, and enjoy their presence.  Allow their ideas and awareness to infect you, and you’ll find yourself expanding in all directions.  You’ll become more honest, more courageous, more compassionate, and so on.
But spend time with people at a lower level of consciousness, and you’ll gradually sink to their level.  Their thoughts will infect you as well, causing you to become more dishonest, more fearful, more apathetic, etc.
Strive to find a balance between spending time with those who raise your consciousness vs. spending time with those you can help.  Learn from those who are a little more conscious, and help those who are a little less conscious than you.  In this manner you serve the highest good of all, expanding consciousness everywhere.
9. Energy
Energy raises your consciousness.  Disease lowers it.
Take care of your physical body, for it is your primary means of interacting with the world.  Energy gives you an ongoing flow of vital life experiences.  But without energy you starve your consciousness.
Eat with an awareness of what you’re consuming.  Exercise with an awareness of how you’re affecting your body and mind.  Before putting anything in your body, consider its effect on your energy, not just in the short term but in the long term as well.  Always ask yourself, “Will this produce energy or disease?”
10. Intention
The intention to raise your consciousness raises it.  The intention to lower your consciousness lowers it.
Consciousness has the capacity to self-expand or self-contract, just as you have the capacity to grow or to commit suicide.  In any given moment, you have the freedom of choice.
By genuinely voicing the intention (or by offering the prayer), “I intend to become more conscious and aware,” you will initiate the expansion of your consciousness.  Holding the intention to improve in any of the previous nine areas will yield a similar effect.
Alternatively, you are perfectly free to lower your consciousness at any time.  While it’s unlikely you would choose to do so directly, you can achieve the same effect indirectly by lowering your performance in any of the previous nine areas.  By choosing to lie, to succumb to fear, to commit acts of cruelty, to remain ignorant, and so on, you put out the intention to lower your consciousness.  And in so doing, you initiate a process that will attract more falsehood, fear, cruelty, ignorance, etc. into your life.
Every thought you hold serves to either expand or contract your consciousness.  There is no neutral.  So choose wisely.

Train Yourself To Fall Asleep In Less Than 30 Seconds.


Does it take you a while to fall asleep at night? Do you find your mind dwelling on various thoughts before you’re able to finally drift off and relax into sleep? Do you find that you just aren’t sleepy enough when it’s time for bed?
Realize that if it takes you 15 minutes on average to fall asleep each night, that’s more than 91 hours per year that you’re wasting. This is the equivalent of spending more than two 40-hour workweeks just lying in bed waiting to fall asleep.
And if you have insomniac tendencies and take more than an hour to fall asleep each night, you’re spending more than nine 40-hour weeks on that pointless activity — every year. That’s a tremendous amount of wasted time.
If you’d like to change this situation, keep reading. I’ll explain the details and share a process for training your brain to fall asleep almost instantly when you’re ready to go to bed.

Drop Caffeine (at Least Initially)

First, if you drink coffee, tea (including green tea and white tea), yerba mate, cola, or any caffeinated beverages on a semi-regular basis, this method won’t work very well at all, so I strongly recommend that you get off all caffeine for at least 2 weeks before you attempt to make improvements in this area. Read How to Give Up Coffeeif you need help with that. I also advise that you drop chocolate during this time as well, including cocoa and cacao, since those contain stimulants too.
Even a small cup of coffee in the morning can disrupt your ability to fall asleep quickly at night. You may also sleep less restfully, and you’ll be prone to awaken more often throughout the night. Consequently, you may wake up tired and need extra sleep.
Simply eliminating all caffeine from your diet can improve your sleep habits tremendously. So if you haven’t already done that, please do that first before you attempt the training method I explain later in this article.
If you really love your caffeine though, the good news is that it’s okay to add it back once you’ve gone through this adaptation training. It will still disrupt your sleep a bit, but once you’ve mastered the habit of being able to fall asleep in 30 seconds or less, then most likely you’ll still be able to continue the habit even if you consume some caffeine during the day.

Train Your Brain to Fall Asleep Faster

A decade ago it might have taken me 15-30 minutes to fall asleep most nights. Sometimes it would take more than an hour if I had a lot on my mind. And very occasionally I could fall asleep within 5 minutes or less if I was very sleepy.
Today it’s fairly normal for me to fall asleep within 30 seconds or less, and often I’m able to fall asleep in less than 1 second. My best is probably around 1/4 of a second.
How do I know this? Because I have a witness that tells me how long I was out. I also know that I was sleeping because I awaken with the memory of a dream. If my sleep time is only a second or a fraction of a second, then it’s obviously a very short dream. Some time dilation occurs though, so a 1-second dream may feel significantly longer… perhaps as if 5-10 seconds have passed within the dream world.
Is this narcolepsy? No, narcolepsy is very different. I don’t just fall asleep at odd times throughout the day, and I don’t have excessive daytime sleepiness. Most days I don’t take any naps. One thing I do have in common with narcoleptics is that I can start having dreams immediately when I fall asleep, whereas most people don’t enter the dream state for at least an hour. I regard this as a positive adaptation though, not a problem or defect.
I can’t normally force myself to sleep when I’m not at all sleepy. But when I’m ready to go to sleep, I can go to sleep very quickly without wasting time trying to fall asleep.
I’m not able to do this 100% perfectly. If I have a stressful day and there’s a lot on my mind at night, I may find it more difficult to relax and go to sleep. But most of the time under normal, average conditions, I can get to sleep within 30 seconds or less.
I reached this point not by the exertion of conscious will but rather through a long-term process of sleep training. So don’t think that there’s some mental trick that you can use right away to make this happen instantly. However, once you’ve trained yourself to this point, the process is effortless. You’ll be able to do it automatically. It will be no more difficult than blinking.

Understanding the Training Process

The training process may take a long time — months or even years, depending on how far you want to go — but it’s not at all difficult, and it needn’t take a serious time commitment. In fact, the training will most likely save you a significant amount of time. The only challenging part is maintaining consistency long enough to get results.
First consider that it’s possible for you to fall asleep faster. Have you ever been really tired and sleepy at the end of a day, and you fell asleep very quickly after getting into bed? Have you ever drifted off while watching a movie or reading a book? Have you ever fallen asleep within less than 2 minutes after lying down? If you’ve done it before, then consider the possibility that your brain already knows how to fall asleep quickly, and if you create the right conditions, then you’re capable of doing this again. You just need to train your brain to do this more consistently.
The main reason that you aren’t falling asleep faster is that you haven’t trained your brain to do so. You may be able to reach that point eventually, but you’re not there yet. Similarly, you may be able to do the splits if you engage in flexibility training, but in the absence of such training, you probably won’t be able to do the splits at all.
If you want to fall asleep faster, you must incentivize your brain to drop all other activity and immediately transition into sleep when you desire to do so. That is the essence of this approach. If there are few consequences for a lazy approach to falling asleep, then your brain will continue to be lazy and inefficient in this area. You haven’t given it a good enough reason to select more efficient behaviors.
Your brain is always active, even during deep sleep, and it operates in different modes of consciousness, including beta (waking), alpha, theta, and delta phases. When you lie in bed waiting for sleep, you’re waiting for your brain to switch modes. An untrained brain will often take its own sweet time making the necessary state change. So you may dwell on other thoughts… or toss and turn… or just lie awake until your brain is finally ready to transition. This is a common experience. Without incentives to become more efficient, your brain will remain naturally lazy by default.
Your conscious mind might very much like to go to sleep, but it isn’t in charge. Your subconscious determines when you fall asleep. If your subconscious mind is in no hurry to fall asleep, then your conscious mind will have a hard time forcing it. In fact, your subconscious may continue to bubble up thoughts and ideas to occupy your conscious mind, distracting you with mental clutter instead of letting you relax and slide into sleep.
A trained subconscious mind is obedient and fast. When the conscious mind says to sleep, the subconscious activates sleep mode immediately. But this only works if you’re feeling at least partially sleepy. If the subconscious doesn’t agree with the need for sleep, it can still reject the request.
The process I’ll share next will teach your brain that putzing around isn’t an option anymore and that when you decide to go to sleep, it needs to transition immediately and without delay.

The Process

The process involves using short, timed naps to train your brain to fall asleep more quickly. Here’s how it works:
If and when you feel drowsy at some point during the day, give yourself permission to take a 20-minute nap. But only allow yourself exactly 20 minutes total. Use a timer to set an alarm. I often do this by using Siri on my iPhone by saying, “Set a timer for 20 minutes” or “Wake me up in 20 minutes.” The first one sets a countdown timer, while the later phrase sets an alarm to go off at a specific time. Sometimes I prefer to use a kitchen timer with a 20-minute countdown.
Begin the timer as soon as you lie down for your nap. Whether you sleep or not, and regardless of how long it takes you to fall asleep, you have 20 minutes total for this activity… not a minute more.
Simply relax and allow yourself to fall asleep as you normally would. You don’t have to do anything special here, so don’t try to force it. If you fall asleep, great. If you just lie there awake for 20 minutes, also great. And if you sleep for some fraction of the time, that’s perfectly okay too.
At the end of the 20 minutes, you must get up immediately. No lingering. This part is crucial. If you’re tempted to continue napping after the alarm goes off, then put the alarm across the room so you have to get up to turn it off. Or have someone else forcibly yank you off the couch or bed when they hear the alarm. But no matter what, get up immediately. The nap is over. If you’re still tired, you can take another nap later — wait at least an hour — but don’t let yourself go back to sleep right away.
I think it’s best to do your nap practice during the day if you can, but you can also do it in the evening, as long as it’s at least an hour before your normal bedtime. Perhaps the best time for an evening nap is right after dinner, when many people feel a little sleepy.
You don’t have to take the naps every day, but do them at least a few times a week if you can. I think the ideal practice would be one nap per day.
The next part of this process is to always wake up with an alarm in the morning. Set your alarm for a fixed time every day, seven days a week. When your alarm goes off each morning, get up immediately regardless of how much sleep you actually got. Again, no lingering. If you need help with this, read How to Become an Early Riser,How to Become an Early Riser – Part II, and How to Get Up Right Away When Your Alarm Goes Off. Those articles have helped many thousands of people improve their sleep habits.
Now when you go to bed at night, seek to go to bed at a time that will essentially require you to be sleeping the whole time you’re in bed in order to feel well rested in the morning. So if you feel you need a good 7 hours of sleep each night to feel rested, and you plan to get up at 5am every morning, then get yourself into bed and ready to sleep at about 10pm. If you take 30 minutes to fall asleep, then you’re getting less sleep than you need, and this is a disincentive to continuing that wasteful habit.
The message you’re sending to your brain is that the time you have to sleep is limited. You are going to get out of bed after a certain number of hours no matter what. You’re going to get up from your nap after a specific amount of time no matter what. So if your brain wants to sleep, it had better learn to go to sleep quickly and use the maximum time allotted for sleep. If it wastes time falling asleep, then it misses out on that extra sleep, and it will not have the opportunity to make it up by sleeping in later. Sleep time squandered is sleep time lost.
When you go to bed whenever and allow yourself to get up whenever, you reward your brain for continued laziness and inefficiency. It’s fine if you take a half hour to fall asleep since your brain knows it can just sleep in later. If you awaken with an alarm but go to bed earlier than necessary to compensate for the time it takes you to fall asleep, your still tell your brain that it’s fine to waste time transitioning to sleep because there’s still enough extra time to get the rest it needs.
Coffee and chocolate are also crutches because if you don’t get enough sleep, your brain can come to rely on a stimulant to keep it going when necessary. If you remove these outs, then your brain will soon connect the dots. It will learn that taking too long to fall asleep equals not getting enough sleep, which means going through the day tired and sleepy. By closing the door on potential outs like stimulants and extra snooze time, you leave only one remaining option for a solution. Sooner or later your brain will determine that going to sleep faster is indeed the solution, and it will adapt by transitioning into sleep much more quickly, so as to secure the full amount of rest it desires.
Instead of continuing to give your brain the message that oversleeping is okay or that stimulants are available, begin to condition it to understand that sleep time is a limited resource. Your brain is naturally good at optimizing scarce physiological resources; it evolved to do so over a long period of time. So if sleep time appears to be a limited resource, your brain can learn to optimize its use of this resource just as it has learned to optimize the use of oxygen and sugar.
If you get sleepy during the day as a result of limiting your sleep time at night, that’s perfectly okay. Take naps as needed. It’s okay to take multiple naps during the day if you need to, but keep them limited to 20 minutes max, and don’t have two naps within an hour of each other. Whenever you get up, stay up for at least an hour.
Once you get used to 20-minute naps — or if you don’t have that much time available for napping — try napping for shorter intervals. Give yourself 15, 10, or even 5 minutes for each nap. I sometimes take 3-4 minute naps (with a timer), which are surprisingly refreshing, but only if I fall asleep quickly.
Teach your brain that a 20-minute nap means 20 minutes of total time lying down. If your brain wants to ruminate during part of that time, it always means less sleep.
Also teach your brain that X number of hours in bed at night is all it gets, and so if it wants to get enough sleep, it had better spend virtually all of that time sleeping. If it spends time on non-sleep activity, it always robs itself of some sleep.
Once you’ve adapted and you’re able to fall asleep quickly when you desire to do so, you can slack off on the training process, ditch the alarm, and wake up whenever you want. Most likely the training will stick. You can even add the caffeine back if you so desire. But for a period of at least a couple months to start, I recommend being strict about it. Take naps regularly, and use an alarm to get up at a consistent time every single day.
I still prefer to get up with an alarm most days. I don’t need it to fall asleep quickly, but I tend to linger in bed more than necessary without the alarm.
If this is too strict for you, I doubt you’ll succeed with this approach. If you give your brain an easy out, it will take that out, and it won’t learn the adaptation you’re trying to teach it here.
Everyone is different, so how long it takes you to adapt depends on your particular brain. I’m sure some people will adapt fairly quickly, within a few weeks, while others may take significantly longer. There are many factors that can influence the results, with perhaps the biggest one being your diet. In general, a lighter, healthier, and more natural diet will make it significantly easier to adapt to any sort of sleep changes. Regular exercise also makes it easier to adapt to sleep changes; cardio exercise in particular helps to rebalance hormones and neurotransmitters, many of which are involved in regulating sleep cycles. If you eat a heavily processed diet (i.e. shopping mostly outside the produce section) and you don’t exercise much, just be aware that I rarely see such people succeed with worthwhile sleep changes of any kind.
One last item I’ll share is that I’m able to fall asleep fastest when I’m cuddling someone, both for naps and when going to bed at night. On my own I can get to sleep in under 30 seconds normally, but when I’m cuddling a nice warm female body, that’s when I can often get to sleep in less than a second. So I invite you to experiment with this if you have a willing cuddle partner who enjoys serving as a human teddy bear.
