             There is a mountain, far beyond the plains and hills, whose great                            summit overlooks the dark valley and the open seas. 
           Neither cloud nor deep mists ever hide its calm face. It is above the                      shadows of day and night.
           From the vast plain, no man can behold it. 
           Some have seen it but there be few that have reached its feet. 
           One in many thousand years gathers his strength and gains that abode                  of eternity. 
           I speak of that mountain top, serene, infinite, beyond thought.
           I shout for joy!  

One day, a man beheld through the opening of a cloud, the calm face of the mountain. He stopped every passer-by, that would stay to give an answer, and inquired of the way that would lead him beyond the mists. 
Some said take this path, and others said take that path. 

After many days of confusion and toil, he arrived among the hills. A man, full in years, wise in the ways of the hills, said, "I know the way. You cannot reach the mountain, O friend, unless you are strengthened by the power that comes from the adoration of the image in yonder shrine."
Many days passed in peaceful worship. 

Tired of worship, he asked of men that seemed great with understanding.
"Yea," said one, "I know the way. But if you would gain the fulfillment of your desire, carry this on you. It will uphold you in your weariness." He gave him the symbol of his struggle. 
Another cried, "Yea, I know the way. But many days of contemplation must be passed in the seclusion of a sanctuary, with my picture of eternity."
 "I know the way," said another, "But you must perform these rites, understand these hidden laws, you must enter the association of the elect and hold fast to the knowledge that we shall give you."
"Be loud in the song of praise of the reflection that you seek," said another. 
"Come, follow me, obeying all things I say. I know the way," cried another.

Eventually, the calm face of the mountain was utterly forgotten.
Now he wanders from hill to hill, crying aloud, "Yes, I know the way, but..."  

          There is a mountain, far beyond the plains and hills, whose great                            summit overlooks the dark valley and the open seas. 
           Neither cloud nor deep mists ever hide its calm face. It is above the                      shadows of day and night.
           From the vast plain, no man can behold it. 
           Some have seen it but there be few that have reached its feet. 
           One in many thousand years gathers his strength and gains that abode                  of eternity. 
           I speak of that mountain top, serene, infinite, beyond thought.

What You Should Know About Sleep

Sleep is a really weird thing, when you think about it. Sometimes when I’m drifting off to sleep, I’ll find myself thinking, “There are tens of millions of people right now lying unconsciously in theirs beds, temporarily paralyzed and experiencing intense hallucinations.”
Because that’s what happens during sleep. It’s crazy, huh?
But why must we all engage in this nightly routine? For most of human history sleep has been a big mystery. It wasn’t until fairly recently that scientists have begun to understand why animals and humans need to sleep. And even those emerging ideas are just hypotheses. When Dr. William C. Dement, who founded the Sleep Research Center at Stanford University and has researched sleep for over 50 years, was asked why we need to sleep, his golden response was: “As far as I know, the only reason we need to sleep that is really, really solid is because we get sleepy.” So despite the ability to peer into the brain with advanced technologies like MRIs and EEGs, sleep remains almost as much of a mystery to us as it was for the ancients.
While we don’t know exactly why we need to sleep, we do know it provides a myriad of benefits, and that if we don’t get enough of it, we risk a plethora of health and mental problems. The funny/sad thing is, even though sleep is an important part of overall health, it doesn’t get the same attention as diet and exercise does. People rarely boast of their propensity for eating mass quantities of Cheetos, but folks love to offer humble-brags about how little sleep they’re getting by on; it’s become a badge of honor to show off how busy one is with more important things. Sleep has unfortunately become associated with laziness – a luxury for the non-go-getter set. Yet, if you want to get bigger, stronger, leaner, and manlier, as well as smarter and more emotionally resilient, you’ll need to be as thoughtful about your sleep as you are about your deadlifting and paleo diet. Sleep is truly one of the most neglected parts of building a foundation for a life of excellence. In fact, the average human spends an astonishing 24 years of their life sleeping; you’d be wise to understand it and make sure you’re getting the most out of it.

Understanding the Sleep Cycle

Before the 20th century, the common belief among scientists and doctors was that our brain basically shut down during sleep and the only parts that remained active were those essential for keeping us alive. However, with the invention of electroencephalography (EEG) and the ability to measure brain waves, that belief changed.
We now know that there are two major types of sleep: 1) Non-REM (quiet sleep) and 2) REM (dreaming sleep). These two cycles alternate with each other over the course of the night.
Non-REM (Quiet) Sleep
Non-REM sleep consists of four stages (or three, depending on who you ask):
  • Stage 1: We’re technically not asleep during Stage 1, but we’re well on our way. We spend about 5 minutes in this phase, though it can last longer. Brain activity begins to slow down; body temperature starts to drop; muscles relax; eyes move slowly from side-to-side. During Stage 1 sleep we lose awareness of our surroundings but we’re still easily jarred to wakefulness. If you’ve ever woken up from a sleep but claimed you were just “resting your eyes,” you were likely roused during Stage 1.
  • Stage 2: This is the first stage of honest-to-goodness sleep. The first time it occurs during the night, it lasts 10-25 minutes before you go to the next stage. During Stage 2 sleep, your eyes are usually still, and breathing and heart rate are slower than when you’re awake. Brain activity is irregular; the EEG will pick up intermediate-sized brain waves intermingled with bursts of fast activity.
  • Stages 3 and 4: Stages 3 and 4 are typically smooshed together by researchers and are called “deep sleep” or “slow wave sleep.” Deep sleep lasts anywhere from 20 to 40 minutes, but declines with age. In this stage, brain activity primarily consists of large, slow waves. Breathing slows and blood pressure drops 20 to 30 percent below awake levels. You’re much less responsive to external stimuli during deep sleep and thus harder to rouse. It’s in this stage that our bodies also repair and renew themselves. At the beginning of deep sleep our pituitary gland releases a pulse of human growth hormone to help with tissue repair and growth. Levels of substances that activate our immune system, like interleukin, increase in our blood.
REM (Dreaming) Sleep
The 4 stages of sleep alternate with REM (Rapid Eye Movement) sleep, which is basically when your mind has a party. Here’s what happens to our body and mind during REM sleep:
  • Brain releases a small amount of a substance called DMT which has intense psychedelic properties
  • Brain activity skyrockets because we’re dreaming
  • Muscles not needed for breathing or eye movement are paralyzed; we can’t move during REM sleep
  • Eyes move back and forth rapidly (hence the name)
  • Blood pressure increases
  • Heart and breathing levels increase to daytime levels
  • Testosterone levels increase
  • Erections regularly occur in men
  • Despite being paralyzed, our sympathetic nervous system is twice as active as when we’re awake
We typically experience three to five REM sessions a night. The first episode lasts just a few minutes, but REM sleep gets progressively longer as the night goes on. The final REM session can last up to an hour.
Sleep Architecture 
A normal sleeper moves between these two sleep patterns in a fairly predictable manner over the course of the night. If you were to get 8 hours of uninterrupted sleep, you’d go through four to five alternating non-REM and REM sessions. Above is a chart that shows a typical sleep cycle during 8 hours of sleep. Notice how REM and Stage 2 begin to alternate as the night progresses.

What Controls Our Sleep

Circadian Clock
Inside your brain there’s an internal clock that governs your sleep and wake cycle. It’s called the circadian clock, and it’s located in the suprachiasmatic nucleus (SCN), a cluster of cells that are part of the hypothalamus. The cycling of the clock (called the circadian rhythm) in humans follows a 24-hour cycle that responds to light and dark in the environment. The circadian rhythm for sleep and wakefulness in humans dips and rises at different times of the day. The desire to sleep is generally stronger between midnight and dawn, as well as in mid-afternoon. The exact cycle will change from person to person.
Zeitgebers (External Cues for Sleep)
While our circadian rhythm is internal and will cycle through sleepiness and wakefulness on a pretty regular basis, external cues called zeitgebers (German for “time giver” or “synchronizer”) also play a role in governing our naturally occurring rhythms. If you change or disrupt certain zeitgebers, you can cause shifts in your circadian rhythm, making it difficult to get to sleep when you’re ready to hit the hay. Below are a few of the most influential external cues that affect our sleepiness/wakefulness cycle:
  • Light. Light is the most influential zeitgeber. Our retinas actually have a direct connection to the SCN. When we’re exposed to light, our brain produces more hormones, like serotonin, that make us feel awake; when it starts to get dark, our brain starts ramping up the sleepy hormone melatonin. The creation of artificial lights in the late 19th and early 20th centuries have been blamed for messing up natural sleep cycles. While exposure to any kind of light can affect circadian rhythms, research has found that exposure to light with blue wavelengths is the most disruptive to melatonin production. Unfortunately, most of us put electronic devices right in front of our faces every night that primarily emit this blue light. If you’ve been having trouble falling asleep, it may be because you’re surfing Reddit on your laptop and looking through Instagram photos on your smartphone late at night. 
  • Exercise. Strenuous activity like exercise can be a cue to delay sleep and stay awake. One study found that nightly exercise was an effective way to delay the onset of melatonin secretion at night, making it more difficult to get to sleep. This can of course be a benefit if you actually don’t want to sleep, which is why a late bout of exercise is helpful when you’re aiming to pull an all-nighter.
  • Negative social interactions. Negative social interactions can contribute to interrupting your internal circadian clock. Disruptive social events like break-ups or the death of a loved one have a tendency to cause shifts in sleep patterns, causing you to toss and turn at night.
One takeaway from this information is that because our sleep cycle is evolved to sync up with something as reliable as the rising and the setting of the sun, varying your daily and nightly routine as little as possible plays an important role in improving the quality of your sleep. 

How Much Sleep Do I REALLY Need?

Every person is different and will require different amounts of sleep to run on all eight cylinders (see, I didn’t say four cylinders). The need for sleep generally follows a bell curve: a few people can get by perfectly fine on as little as 4 to 6 hours of sleep (some folks actually have a genetic variation that gives them more intense sleep sessions, which allows them to get by on less); the vast majority of people need 7 to 8 hours; and a few need as much as 9 to 10 hours of sleep.
You’ve likely read articles highlighting super successful individuals who supposedly get by on just 4 hours of sleep a day. While it’s possible that they’re one of those fortunate mutants who don’t need much sleep, it’s likely that they’re actually sneaking in a nap or two during the day, and thus getting more sleep than they let on. (Thomas Edison was like this; he liked to boast that he only got 3-4 hours of sleep every night…while neglecting to mention that he took one or two 3-hour naps every day.) Either that, or they’re a walking zombie, who could be performing way better in their day-to-day life than they are.
As you get older, you need less sleep. Generally, total sleep decreases from about 7.5 hours at age 20 to 7 hours at age 40 to about 6 hours at age 60. Not only do we sleep less, our sleep architecture changes as well. Stage 1 and 2 sleep increases while Stage 3 and 4 decreases. You’ll also find yourself waking up more at night. Why is this? Well, melatonin production decreases as we age and the body’s overnight dip in temperature, which helps with staying asleep, becomes less pronounced as well.
The best way to calculate how much sleep you need is to simply listen to your body. If you find it easy to get out of bed, aren’t sleepy during the daytime, don’t have any problems concentrating, are generally in a good mood, and you feel fully rested after a night of sleep, well, then you found your optimal amount of sleep.

The Horrible, No Good, Very Bad Consequences of Sleep Deprivation

A whole host of things go wrong when you don’t get the amount of sleep your mind and body needs. Sleep deprivation comes in two types: complete and partial.
Complete Sleep Deprivation
Complete sleep deprivation happens when you go a night without sleeping at all. Complete sleep deprivation can cause immediate decreases in concentration and hurts long-term and working memory (which means that all-night cramming session for your history test might actually make you more forgetful). You’ll also experience increases in cortisol, which makes you feel stressed and lowers testosterone levels.
(On the flip side, skipping a night’s sleep can create feelings of euphoria, and boost your brain’s motivation and desire for reward. This can lead to poor decision-making and risky behavior, but it is also found that an occasional all-nighter is exactly what you need to crack the code on a tough post you are working on. The key here is occasional; remember that a low dose of short-term stress can actually be good for you, while chronic stress is nothing but bad news.)
You likely won’t experience very many periods of complete sleep deprivation in your life (unless you’re one of those all-nighter-loving architects). Our bodies and brains just can’t take it. After a few days of continual non-sleep, your body will simply force it upon you. In fact, you’d die of sleep deprivation before you’d die of starvation.
Partial Sleep Deprivation
Partial sleep deprivation happens when you get some sleep but not 100% of what you need — basically a bad night’s sleep. When you experience one night of partial sleep deprivation, you can function at normal levels the next day, but you don’t feel great. Problems with partial sleep deprivation start showing up after two or three nights of less-than-ideal sleep. You’ll become irritable and you’ll notice a drop in your concentration and work performance; in fact, after only two weeks of getting 6 hours of sleep a night, your reaction time will be similar to someone with a blood alcohol level of .1%, which is considered legally drunk. If you go several weeks, months, or years (we’re talking insomniacs here) with partial sleep deprivation, well, you’re going to be in a world of hurt. Here’s a breakdown of some of the things that will happen when you’re partially sleep deprived for an extended period of time:
  • Impaired nerve cell generation
  • Increased risk for depression
  • Decrease in pre-frontal cortex activity, which makes us more impulsive and unable to control our emotions
  • Increased emotional and mental stress
  • Reduced grey matter in brain
  • Increased blood pressure and chances of heart disease
  • Increased chance for obesity and diabetes
  • Reduced testosterone levels
  • Increased mortality rate
So yeah, if you adopt the maxim that you’ll sleep when you’re dead, you may get there faster than you’d anticipated. Unfortunately, people have this idea that they can just adapt to less sleep; that all those bad things won’t happen because their body will simply get used to being short-shrifted on slumber. But the research suggests that’s simply not true. Whenever you don’t get the sleep your body needs, you slowly begin to accumulate “sleep debt” (the amount of sleep your body’s in the hole for). The more sleep debt you have, the more your cognition and health decreases. To reverse the problems that come with sleep deprivation you have to repay the debt that has accumulated. If your sleep debt has been building for days, weeks, or months, paying it down is possible by consistently increasing your sleep time.
If you’ve had a string of shortened sleep sessions over a week, several days of getting the sleep you need, plus an additional hour or so per night, should get you square with your body’s sleep debt.
If you’ve accumulated hundreds or thousands of hours of sleep debt due to months of bad sleep, you’ll need several weeks of getting the sleep you need plus an hour or more with each session to get your debt paid down.
We’re able to repay our sleep debt, in most cases, because our deprived bodies sleep in a more efficient manner when we start getting the sleep we need by skipping through Stages 1 and 2 faster and getting to the more restorative Stages 3 and 4.
If you’ve been carrying your sleep debt for years, researchers aren’t sure restoring it is even possible; it may cause permanent damage to your physical and mental faculties.

The Benefits of Sleep

So we know that not getting enough sleep is bad for us, but what are the benefits of getting a good night’s sleep? There are a myriad:
  • Strengthens immunity
  • Increases muscle mass
  • Decreases body fat
  • Increases testosterone
  • Lessens crankiness
  • Cleans out your brain of toxins
  • Decreases inflammation
  • Spurs creativity
  • Improves athletic performance
  • Increases focus and attention
  • Decreases stress
  • Improves memory
Everybody’s searching for that magic pill or obscure hack that will improve their life on every level. Meanwhile, the secret to being stronger, happier, and smarter has been staring them in the face the whole time. They just can’t see it because there’s a computer or tablet blocking their view. So if you’re reading this late at night, and you’re tempted to check out just a “few more things” before your turn in, shut the lid of your laptop, and get to bed, my friend.

The master sculptor surveyed the different blocks of marble at the quarry.
In his lifetime he had learned that there existed a "suchness" to every piece of stone.
Finding that suchness and releasing it to its true life had been the secret of the sculptor's success. "Ah-ha," he would say.
"There is a heroic figure locked in that piece and a saint trapped inside that other one. But where will I find the stone from which I will sculpt my masterwork, a glorious statue of the Buddha?" He had been searching for what he called the "Buddha block" for over forty years and now he felt his energies waning.
He had traveled to the great quarries of the world: Italy where Michelangelo had mined 
his stone, Vermont where the stone glowed with light, and to obscure regions of the mountains of China.
Nowhere could he find that one perfect slab from which he knew he could release the most perfect likeness of Buddha. He consulted experts from around the world. He hired a specialist to scour obscure areas. No success.
In search of consolation, he sought out a local Zen priest, who headed a small temple just at the end of his street.
When he explained his fruitless search, the priest smiled and said, "No problem."
"Do you mean you can tell me where I might find the perfect material from which I can release the Buddha of my dreams??" said the excited sculptor.
"Of course."
"Over there," said the priest, pointing to a stone well in the courtyard. 
The excited sculptor ran to the well and looked down. There he saw his own image looking back at him.

Back to the Future

"Mother, what is water?" asked the baby fish of the mother fish.
"Water is what you swim in. Water is what you're mostly made of." 
"But where is it?"
"All around you." 
"But I can't see it," said the baby.
"Of course you can."
"And I'm made of water?"
"And after I die..?"
"You go back to being water," said the mother.

A gifted young painter of extraordinary talent had been apprenticed to a renowned painter, who when he recognized the boy's gifts became intensely jealous.
"No, that is not the way to do it!" he would shout. "You will do better painting houses than pictures." 
Slowly the boy's confidence ebbed. No matter how hard he tried, the painter found fault and humiliated the boy in front of the other students. 
One day the painting assignment was goldfish. The boy closed his eyes and called up a splendid fat fish from his uncle's pond. 
This he painted. 
"No. No. No!" screamed the teacher and threw the boy's picture into the water, where to everyone's amazement the painted fish proceeded to swim away.

Expert's Dilemma

Once there was a monk who was an expert on the Diamond Sutra, and as books were very valuable in his day, he carried the only copy in his part of the world on his back. He was widely sought after for his readings and insight into the Diamond Sutra, and very successful at propounding its profundities to not only monks and masters but to the lay people as well. 
Thus the people of that region came to know of the Diamond Sutra, and as the monk was traveling on a mountain road, he came upon an old woman selling tea and cakes. 
The hungry monk would have loved to refresh himself, but alas, he had no money.
He told the old woman, "I have upon my back a treasure beyond knowing -- the Diamond Sutra. If you will give me some tea and cakes, I will tell you of this great treasure of knowledge." 
The old woman knew something of the Diamond Sutra herself, and proposed her own bargain. 
She said, "Oh learned monk, if you will answer a simple question, I will give you tea and cakes."
To this the monk readily agreed. 
The woman then said, "When you eat these cakes, are you eating with the mind of the past, the mind of the present or the mind of the future?"

No answer occurred to the monk, so he took the pack from his back and got out the text of the Diamond Sutra, hoping he could find the answer. 
As he studied and pondered, the day grew late and the old woman packed up her things to go home for the day. 
"You are a foolish monk indeed," said the old woman as she left the hungry monk in his quandary. "You eat the tea and cakes with your mouth."

The Trap

A famous teacher took his pupils into a clearing in the forest that was known as a home for wild monkeys. There he took a hollow gourd with a small hole and inserted sweetened rice (a favorite of monkeys). Then he chained the gourd to a stake and waited with his class. 

Soon a very large monkey approached, sniffed the rice, inserted his paw, and screeched in frustration when he was unable to withdraw his paw (now a fist) through the narrow opening. Just then a leopard approached and hearing the monkey screeching decided to have monkey for his dinner. 
"Let go of the rice. Run!" screamed the pupils, but to no avail because the monkey in his hunger for the rice, refused to let go and was as a consequence caught and eaten by the leopard.

 "What was the trap that killed the monkey?" asked the master. "Rice," said one student. "The ground," said another. "No," replied the wise teacher. "The trap was greed." 

“A trap is only a trap if you don't know about it. If you know about it, it's a challenge.”
