| driven by natural mechanics and it can really take the mind to
| different places. Combines well with cannabis.

| Safety note: don't drown.

|
| Way I see it is, we humans are the most sophisticated
| creatures on our planet. Our birth onto earth is a natural
| process by all means. By natural, I mean we are a product of
| nature after all. We humans try to understand the nature
| around us including ourselves, which is what we termed as
| science. Our scientific thought itself is a product of
| nature, and they translate to our endeavors and curiosity to
| unravel the secrets of reality.
|
| These visions that I spoke about are nothing but the universe
| speaking to these great rishis. By universe, I mean nature
| itself. Nature is bestowing knowledge upon its own creations
| to aid them in understanding itself! The same nature that has
| imbued life into our bodies when we are born. The same body
| which will eventually turn to soil after it has run its
| course.
|
| Now, you might wonder, why nature is not bestowing these sort
| of gifts upon you? Frankly, I do not know myself. It is what
| it is. On the bright side, nature has bestowed the most
| fortunate gift of being born as a human being which almost as
| a law of nature makes the heights you can go to limitless. No
| other creature has the same benefits as human beings. We are
| born with both curiosity to ask questions and intelligence to
| analyze and infer profound meanings from their answers.
|
| While "we", the ordinary humans live for about a 100 years
| before forsaking our bodies, however there are people who
| live for 1000s of years. It's a realm of possibility not yet
| uncovered by modern science.
|

|
| That only came into picture recently during the last ~2000
| years. The ancient knowledge I am referring comes from way
| before.

| carbon dioxide in the blood will trigger your brain stem to
| breathe. By removing carbon dioxide from the blood through
| deep breathing, this impulse to breathe from the brain stem
| is lowered.
|
| In short, the lower the level of carbon dioxide, the longer
| you can hold your breath. The impulse is just not triggered
