I have been studying and practicing tibetan buddhism for a little over a year now, particularly dream yoga, but branched into some of the other practices. I'm always a skeptic but it is fascinating some of the stuff they can do. There is scientific evidence they can raise and lower their body temperatures through meditation, withstanding great heat/cold and deprivation conditions. I've played around with deprivation and what it has done for my mental health and body has surprised me. I'm but a novice, but I absolutely believe they are tapping into something scientific about the body/mind that is still unknown.

There are reasons to be extremely skeptical about some of their claims, but, some of it is very interesting and credible.

If TRUE and consciousness is eternal (using whatever framework you like), the idea of death becomes double sided. On one hand, physical death is sad as it's the end of this physical 'epic story' before our consciousness moves onto a new body/story. On the flip side, approaching body death is a sort of a temporary great relief as we are immortal and cannot actually die. I.e. After ten thousand years of being alive, a vampire looks forward to sleeping in their coffin at night.

There are stories about bodies of Christian monks that did not decompose for a log time after the dearth. Modern take on it attributes it to the climate in caves where the body was put after the dearth. But another important part was diet. Often the well-preserved bodies were of those who had eaten only rough bread and water for months and years before the dearth.

So I suspect both of the factors are at the play here as well.

The research mentioned in the article (which indicates no EEG activity): https://pmc.ncbi.nlm.nih.gov/articles/PMC7876463/

Here's the documentary referred to: https://www.imdb.com/title/tt21945758/

It's rentable at the usual places. I might check it out.

Some of these esoteric states are really weird, and it seems crazy to me that we are only now investigating them. This isn’t just “energy” woo that can’t be measured, there are clear physical phenomena.

Another good one is Niroda Samapatti (cessation) where advanced meditators can momentarily cease awareness https://awakeningdharma.org/havard-study-on-nirodha-samapatt...
