Health and fitness learnings for May: a 10 minute walk after a meal can reduce glucose response by 30-35%

Stop Eating All Day (and snacking your kids): Most Americans eat 11 times over a 15-hour period – this is stressful for the body; the body needs time for insulin and glucose to come down

The frequency of aerobic bouts seemed to be more important for their association with health outcomes than the overall duration of daily activity. Concordantly, recent research suggests that short bouts of physical activity can have a strong health-promoting effect

“Watching the news is how you stay on top of other people’s agendas. Taking a walk is how you stay on top of yours.” — Johnny Uzan

As basic as this sounds, full exhalations are seldom practiced. Most of us engage only a small fraction of our total lung capacity with each breath, requiring us to do more and get less. One of the first steps in healthy breathing is to extend these breaths, to move the diaphragm up and down a bit more, and to get air out of us before taking a new one in.

Meditation (mean rating = 5.8), bright lights in the morning (5), cold shower (4.7), and masturbation abstinence (4.1) also got impressive to pretty good ratings.

Spermidine has most significant documented lifespan extension
-studied in naked molerats — don’t age because they produce enormous amounts of spermidine
-most naturally found in: beans; lettuce; wheat germ

This argues that ED and CVD are different manifestations of a systemic arterial damage and, due to the smaller diameter of penile arteries, ED occurs earlier than IHD, stroke or peripheral artery disease (PAD) with an equal extent of artery damage

A meditation compendium: learnings and esoterica on the benefits and practice of meditation

I’ve done bits of meditation for 10+ years, but my standards are laughably low: I consider 5 minutes a day as an achievement :)

And thus I’m always reminded of the saying, “if you don’t have time to meditate for 5 minutes, then you should meditate for 10 minutes”.

Guess I’m not wise enough yet!

All the below is copied verbatim from various sources, but mistakes mine:

Brain changes. People who meditated showed increased activity in the left-anterior part of the brain. Increased activity in this area is associated with positive feelings and emotions. This suggests that meditation makes changes in the brain that help us feel better.

Immune boost. The meditation group also had a stronger response to the flu vaccine. They produced more antibodies against the flu, and their bodies are better equipped to fight off the virus compared to the non-meditators

Meditation like a massage for your brain

a state of profound meditation called samadhi. When meditation becomes very deep, breathing becomes slow, steady, and even, and the windows of the senses close to all outward sensations. Next the faculties of the mind quiet down, resting from their usually frantic activity; even the primal emotions of desire, fear, and anger subside. When all these sensory and emotional tides have ceased to flow, then the spirit is free, mukta –at least for the time being. It has entered the state called samadhi. Samadhi can come and go; generally it can be entered only in a long period of meditation and after many years of ardent endeavor. But one verse (5: 28) adds the significant word sada, “always.” Once this state of deep concentration becomes established, the person lives in spiritual freedom, or moksha, permanently. This is extremely rare.

Consider washing the dishes the most important thing in life. Washing the dishes is meditation. If you cannot wash the dishes in mindfulness, neither can you meditate while sitting in silence.

Human beings are animals; meditation is one way (among many) to deny our animal nature and perhaps reach a higher spiritual plane

The eighth-century Buddhist adept Vimalamitra described three stages of mastery in meditation and how thinking appears in each. The first is like meeting a person you already know; you simply recognize each thought as it arises in consciousness, without confusion. The second is like a snake tied in a knot; each thought, whatever its content, simply unravels on its own. In the third, thoughts become like thieves entering an empty house; even the possibility of being distracted has disappeared.

The dev bites / bytes code guy email about meditation advice
– Meditation is uninteresting repetition, again and again, no matter the technique. It’s only natural to find it uneasy.
– This is not a race. It’s the opposite of a race. The faster you try to go, the slower you will progress. Yet efforts will lead to results. You have to be motivated without avidity, and it’s not an easy balance to find.
– There is a huge difference in effects, between a casual practice (a few minutes, some of the days) and a robust practice (long sessions every day).
– It’s a long term work. It’s, in fact, a life work. Our teacher jokes that at the center, we are at “Vipassana Kindergarden”. We are just beginning. Now we have to carry on and on. Half of the secret of success is simply showing up, every day.

I have been practicing meditation for 15 years, sometimes in batch of 100 hours.

The more I practice, the more the time slows down. Not just while meditating, but after the fact as well. Although it fluctuates and I’m not back to my kid self, it feels that I have tremendously more time now than a few years ago.

I suspect that it’s tied to how much present you manage to be.

When you are a kid, you are deeply immersed in whatever you are doing, and less and less so after that, especially in our age of distractions, multitasking, and intellectual work loads.

I think that the more you are immersed in the daily boring stuff, like just walking, doing chores, or taking your shower, the more you register the time you spend doing said activity, and the time seems to pass slowly.

In fact, I am sometimes under the impression my minutes, not just feel longer, but actually contain more, because I do so many things and then looking at the clock, it hasn’t moved much. This sensation increases when I meditate a lot.

The Buddha withdrew for six years, then returned for forty-five. But each year was likewise divided: nine months in the world, followed by a three-month retreat with his monks during the rainy season. His daily cycle, too, was patterned to this mold. His public hours were long, but three times a day he withdrew, to return his attention (through meditation) to its sacred source

The right brain is in charge of present-moment awareness, and this is the part of the brain that meditation takes to the gym. Essentially, the longer we meditate, the more we’re able to balance the right and left hemispheres of the brain. The result of this is more attention, awareness, and computing power for the task at hand.

Chen: For the overwhelming majority of Asian Buddhists, Buddhism is a devotional practice. Bowing to images of deities, burning incense, worshiping at an altar — those are all fundamental elements of Buddhist practice. There is this acknowledgement of worshiping higher beings. Meditation was not at all a mainstream lay practice in Buddhism

“Meditation is a high interest savings account for your time”

As a novice monk, several times a day I had to light incense to offer on the altar of the meditation hall. I was taught to pick up the stick of incense with both hands, the left hand on top of the right hand, which picks up the stick of incense. A stick of incense is very light. Why do you have to use both hands? The idea is that you have to invest one hundred percent of yourself into this simple act of picking up an incense stick.

“meditation is a non-pharmaceutical Ritalin” – Daniel Goleman

“meditation is as deep and as powerful a tool as we have” – Waitzkin

Meditation is not about feeling good. It’s about feeling what you’re feeling with good awareness. Plot twist: Eventually that makes you feel good

Meditation has been linked to reduced activity in the default mode network, which is associated with self-referential thoughts and mind-wandering. This reduction can lead to an enhanced ability to focus on the present moment and increased self-awareness.

I’ve come out of (non-psychedelic-enhanced) meditations crying. I’ve sat and stared at the traffic outside my window for as long as I might normally have watched a TV show. I’ve had profound creative unlocks I’ve never experienced without drugs or other extreme state changes. I’ve even had brief moments of the fractal vision and plants breathing (IYKYK). It is not the same as a psychedelic experience, but they’re neighbors

Your best decisions come from stillness. Stillness is amplified in nature & meditation.

People who exercise, meditate, or do yoga to get high usually report that their experiences get better and better over time, which is a great contrast to the reports of heavy users of drugs.

Every time you meditate is like making a deposit in a bank (Maharishi)

Even the gods envy those who are awakened and not forgetful, who are given to meditation, who are wise, and who delight in the repose of retirement (from the world).

There’s concrete evidence that meditation calms your brain similar to valium. Actual structural and measurable changes within brain itself

Intensive meditation, even after only one day, can also affect gene regulation in your brain through similar mechanisms. Attending a monthlong meditation retreat reduces the expression of genes that affect inflammation, and experienced meditators can reduce inflammatory genes after just one day of intensive meditation.

Hindu meditation practices have long understood the benefits of sound, especially through the chanting of “Om.” This sound, central to many Hindu traditions, is more than a symbol; it’s a powerful tool that engages the vagus nerve, known for its role in regulating stress and relaxation responses. The act of humming, inherently part of chanting Om, creates a gentle, soothing vibration. This process not only brings a physical dimension to meditation but also enhances the spiritual experience, as the sound of Om is said to represent the universe’s primal sound.

I emailed the writer. I was struck again by his reply, some of which I’m sharing verbatim below (with his permission):

Daily Habits Checklist (May 15th – June 11th): A painter, who became Picasso

Another good 4 weeks and the progress I believe is starting to show, at least in private. The big gap in late May was due to a family cruise which was a great time. And all that white space on Friday May 26th was the result of a delayed flight. I suppose I *could* meditate and do back stretches while waiting at the terminal, but am averse to public attention…

My music habits have been moved to their own category. These include practicing the piano and guitar, and writing song lyrics. Thus they aren’t here, on the main list. But maybe I’ll include them in future updates. My goal is to start publishing songs soon. They probably won’t sound very good :/

Some thoughts on the habits…

Waking early: Your partner’s sleep schedule has a big impact on yours. If your sleep and wake cycles aren’t in sync, then one of you (usually both of you) will suffer. If you can’t get in sync, consider sleeping in separate beds and ignore the social stigma…? :)

Pushups: Seeking ways to “exceed my level”, in the words of Bruce Lee. In this case, eg, decline pushups

Meditate: Still remains hard, after all these years. Why?

My mother said to me, ‘If you are a soldier, you will become a general. If you are a monk, you will become the Pope.’ Instead, I was a painter, and became Picasso.

Here’s why I track habits this way.

Thanks for reading!

11 excerpts from Siddhartha by Hermann Hesse: “Wisdom that a wise man attempts to impart always sounds like foolishness to someone else”

Siddhartha by Hermann Hesse

I recently finished Siddhartha [Kindle] by Hermann Hesse and highly recommend the book. It’s a fast and flowing read and a powerful story, especially if you’re into Eastern philosophy and Buddhism. Siddhartha is the story of a man, a seeker of wisdom and truth, whose life parallels that of Gautama, the original Buddha. Hermann Hesse has a wonderful and unique writing style and I wanted to share some of my favorite excerpts from the book.

**

“Siddhartha,” he said, “why are you waiting?”
“You know why.”
“Will you go on standing and waiting until it is day, noon, evening?”
“I will stand and wait.”
“You will grow tired, Siddhartha.”
“I will grow tired.”
“You will fall asleep, Siddhartha.”
“I will not fall asleep.”
“You will die, Siddhartha.”
“I will die.”

The Brahman fell silent and remained silent for so long that the stars in the small window wandered and changed their relative positions, ‘ere the silence was broken. Silent and motionless stood the son with his arms folded, silent and motionless sat the father on the mat, and the stars traced their paths in the sky.

“Wisdom cannot be imparted. Wisdom that a wise man attempts to impart always sounds like foolishness to someone else…Knowledge can be communicated, but not wisdom. One can find it, live it, do wonders through it, but one cannot communicate and teach it.”

“Govinda,” Siddhartha spoke to his friend. “Govinda, my dear, come with me under the Banyan tree, let’s practise meditation.”

…this smile of Siddhartha was precisely the same, was precisely of the same kind as the quiet, delicate, impenetrable, perhaps benevolent, perhaps mocking, wise, thousand-fold smile of Gotama

“What is meditation? What is leaving one’s body? What is fasting? What is holding one’s breath? It is fleeing from the self, it is a short escape of the agony of being a self, it is a short numbing of the senses against the pain and the pointlessness of life. The same escape, the same short numbing is what the driver of an ox-cart finds in the inn, drinking a few bowls of rice-wine or fermented coconut-milk…”

He soon saw that Siddhartha knew little about rice and wool, shipping and trade, but that he acted in a fortunate manner, and that Siddhartha surpassed him, the merchant, in calmness and equanimity, and in the art of listening and deeply understanding previously unknown people.

Slowly, like humidity entering the dying stem of a tree, filling it slowly and making it rot, the world and sloth had entered Siddhartha’s soul, slowly it filled his soul, made it heavy, made it tired, put it to sleep.

“Most people, Kamala, are like a falling leaf, which is blown and is turning around through the air, and wavers, and tumbles to the ground. But others, a few, are like stars, they go on a fixed course, no wind reaches them, in themselves they have their law and their course.

“It may be important to great thinkers to examine the world, to explain and despise it. But I think it is only important to love the world, not to despise it, not for us to hate each other, but to be able to regard the world and ourselves and all beings with love, admiration and respect.”

“Have you also learned that secret from the river; that there is no such thing as time?” That the river is everywhere at the same time, at the source and at the mouth, at the waterfall, at the ferry, at the current, in the ocean and in the mountains, everywhere and that the present only exists for it, not the shadow of the past nor the shadow of the future.”
