I travel pretty often to the opposite site of the planet, and the best way I’ve found to sleep in an airplane, train, or car seat is a $1 beach ball (from a toy store) inside a pillow case. It can be adjusted to suit almost any sleeping position, it compresses well in luggage, and it costs almost nothing. I hope this helps you sleep better on long journeys.
When speaking of attachments, desires, cravings, etc., people often seem to focus on positive things: love of/for pleasure, family, friends, a certain place, etc. However, attachments can also be negative. For example: an activist might hate corruption or injustice, a police officer might hate crime or criminals, a military officer might hate foreign aggressors, a terrorist might hate another religion or ethnic group, an abused person might want revenge, an abusive person might want to exploit others, a corporate boss might want to conquer every competitor, a politician might want dictatorial power, and so on. Of course, most people probably have a mixture of positive and negative attachments.
As I understand, in Buddhism, rebirth happens because of any attachment to this (or any) world, not only positive attachments. The Buddha also seems to have been attached to “the pleasure of renunciation, the pleasure of seclusion, the pleasure of peace, the pleasure of self-awakening” (AN 8.86), which are perhaps attachments leading to nirvana.
Stephen Hawking, one of the most brilliant physicists ever to have lived, used to publicly say this every year or two, because it is perhaps the most important thing humanity should be doing but is only barely/slowly doing. Now that he is gone, I’ll repeat it: for the survival of our species, humans really need to leave this tiny, fragile little planet as quickly as possible. At national and global levels, instead of putting resources into fighting with each other and building things on this planet, we should be focusing on building space stations, fast ships, and colonies on other planets and in other solar systems. Currently, our entire species could be wiped out by global warming, over-population, nuclear war, one large epidemic, asteroid, solar flare, and on and on. We need to go and spread out, now.
Here are two early Buddhist quotes I don’t often hear in today’s entertainment-saturated, militaristic societies:
On one occasion the Blessed One was staying near Rajagaha in the Bamboo Grove, the Squirrel’s Sanctuary.
Then Talaputa, the head of an acting troupe, went to the Blessed One and, on arrival, having bowed down to him, sat to one side. As he was sitting there he said to the Blessed One: “Lord, I have heard that it has been passed down by the ancient teaching lineage of actors that ‘When an actor on the stage, in the midst of a festival, makes people laugh & gives them delight with his imitation of reality, then with the breakup of the body, after death, he is reborn in the company of the laughing devas.’ What does the Blessed One have to say about that?” …
[The Buddha replied:] Any beings who are not devoid of passion to begin with, who are bound by the bond of passion, focus with even more passion on things inspiring passion presented by an actor on stage in the midst of a festival. Any beings who are not devoid of aversion to begin with, who are bound by the bond of aversion, focus with even more aversion on things inspiring aversion presented by an actor on stage in the midst of a festival. Any beings who are not devoid of delusion to begin with, who are bound by the bond of delusion, focus with even more delusion on things inspiring delusion presented by an actor on stage in the midst of a festival. Thus the actor — himself intoxicated & heedless, having made others intoxicated & heedless — with the breakup of the body, after death, is reborn in what is called the hell of laughter. But if he holds such a view as this: ‘When an actor on the stage, in the midst of a festival, makes people laugh & gives them delight with his imitation of reality, then with the breakup of the body, after death, he is reborn in the company of the laughing devas,’ that is his wrong view. Now, there are two destinations for a person with wrong view, I tell you: either hell or the animal womb. … (Samyutta Nikaya 42.2)
Similarly about soldiers:
“Then Yodhajiva the headman went to the Blessed One and, on arrival, having bowed down to him, sat to one side. As he was sitting there he said to the Blessed One: “Lord, I have heard that it has been passed down by the ancient teaching lineage of warriors that ‘When a warrior strives & exerts himself in battle, if others then strike him down & slay him while he is striving & exerting himself in battle, then with the breakup of the body, after death, he is reborn in the company of devas slain in battle.’ What does the Blessed One have to say about that?” …
[The Buddha replied:] When a warrior strives & exerts himself in battle, his mind is already seized, debased, & misdirected by the thought: ‘May these beings be struck down or slaughtered or annihilated or destroyed. May they not exist.’ If others then strike him down & slay him while he is thus striving & exerting himself in battle, then with the breakup of the body, after death, he is reborn in the hell called the realm of those slain in battle. But if he holds such a view as this: ‘When a warrior strives & exerts himself in battle, if others then strike him down & slay him while he is striving & exerting himself in battle, then with the breakup of the body, after death, he is reborn in the company of devas slain in battle,’ that is his wrong view. Now, there are two destinations for a person with wrong view, I tell you: either hell or the animal womb. … (Samyutta Nikaya 42.3)
Since there is a Jewish Buddhist movement, here is a list of ways in which (Theravada or early) Buddhism and Judaism are, as I understand, more similar to each other than either is to Christianity:
- In both, though there are things on which most members of each religion agree, there is no firm dogma, because the spiritual goal (experiencing God or Nirvana) is thought to be beyond mundane human thought. Individuals are free to explore their own spiritual feelings and beliefs, and to develop their own understandings. Prophets, Messiahs, the Buddha, and monks are people who may have had an especially clear or rich spiritual experience, but they are not God(s) themselves. Said another way: both religions are more orthopraxic than orthodoxic (i.e., less faith-based, more focused on what people do and experience than on what they believe).
- Absolute reality, God, etc. is usually thought to be some kind of unity or single substance, not a trinity, a hypostatic union (hybrid God-man), etc.
- Both are/were largely aniconic (Buddhism was in the early days) and prohibit giving anything a higher status than God or nirvanic beings.
- Like devas in Buddhism, early Judaism seems to have acknowledged polytheism (e.g., El becoming YHWH, “You shall have no other gods before me,” etc.), but neither made polytheism central to their religion.
- Hell is not forever. In Judaism, hell is more like Catholic purgatory and lasts only a short time, so that God can teach sinners a lesson. Those souls who are too bad to be redeemed are either destroyed by God, which seems much more compassionate to me than eternal torment, or continue to exist in a remorseful state. In Buddhism, the length and depth/badness of a hellish life varies based on one’s karma, with the worst hell being called avici. Both also find rebirth/reincarnation possible.
- Both generally lack a notion of original sin, though in Buddhism, the mind that is reborn has typically had many past lives and has accumulated many both good and bad traits. Both see people as a mixture of good/selfless and bad/selfish impulses, and see a Middle Way-type balance to be necessary for successfully living in the world (e.g., a person has to be a little selfish in order to have food to eat, to do a job, etc.).
- Less focus is placed on external forces (e.g., the devil, praying to angels or saints, God(s) taking physical form, etc.), which are usually considered to be metaphorical. Unlike how Christians often interpret it literally, the oft-quoted line from Genesis 1:27, that man was made in the image of God, is usually taken in Judaism to mean that a human’s nature, essence, or capacities for things like reason and intuition are similar to God’s, not that God literally has a human-like (or any corporeal) form.
- Both Buddhism’s precepts, the Brahmaviharas, etc. as well as Judaism’s kosher rules are concerned with how to kill animals as sparingly and humanely as possible. In both, the brief five-to-ten precepts/commandments are just a categorization or introduction to a much longer set of vinaya/commandments about many aspects of life.
- Both Buddhists and Jews do merit-making activities, especially as regards dead family members: https://ohr.edu/explore_judaism/ask_the_rabbi/ask_the_rabbi/1065
Thinking about how, according to Einstein, things that travel at/near the speed of light don’t/hardly age compared with the rest of the universe, I wonder if encoding one’s mind on light (or another physical phenomenon that travels at the speed of light in a vacuum, such as electromagnetism) is how beings (e.g., devas) could approach immortality. To live for as long as possible, because anything less than perfect light speed means aging and eventual death, they might have to either stay in as perfect of a vacuum as possible (i.e., deep space or the voids between galaxies), which I imagine would be a very dull way to live (e.g., going around in circles in utter nothingness forever), or might have to find some way to fly forever at light or faster-than-light speed (e.g., using an Alcubierre drive). Gravity wells have a similar effect on time (e.g., time moves slightly slower at the center of the Earth than at the surface), but it is unclear how anything could survive at the center of enough mass to practically stop time relative to the rest of the universe (e.g., inside a supermassive black hole).
Several medical doctors over the years have told me that, though it is unhealthy to be very overweight or obese, it is a good idea to be a little overweight (i.e., on the high end of the healthy BMI range for your height), because if you ever become very sick and can’t eat for a week or two, your body will survive on whatever fat and muscle mass you have. They have also told me that being very thin can worsen osteoporosis, because it takes more bone strength to resist the pull of gravity on a heavier body, and the body automatically adjusts for this.
After having once asked a nutritionist and done my own research about how to healthfully maintain enough weight, here are the conclusions I reached:
- Protein hurts the heart the least, is easiest to burn off through exercise, and low-fat protein (e.g., from lean meats like chicken and fish, nuts, beans, etc.) is healthiest for the heart and arteries.
- The body needs a certain amount of fat, and unsaturated fat (e.g., from nuts, vegetable oils, soy milk, etc.) is usually healthier than saturated fat (e.g., from dairy, beef, or pork).
- In order to gain or maintain weight, one must have a surplus of calories. It’s usually easier to eat a lot, if one eats slowly or frequently, though this can be hard on the teeth.
