Meditation: Humans Compared to Turtles
Experimenters thought they killed a yogi when they put him in an underground pit for 8 days. After about a day buried, his heart monitor was a flatline and stayed this way for 6.5 days. An article in News in Physiological Sciences compared this to the ability of some turtles to stop their heart for as long as 6 months at the bottom of a pond. At the time of the experiment, Yogi Satyamurti was 70 years old and obviously an advanced meditator. What he did while underground was similar to hibernation. This means that advanced meditation may be a level of consciousness separate from wakefulness, dreams, and deep sleep that has evolved in Homo sapiens as an adaptation to harsh environments. I can’t find anything else on the internet about it. The original article is available online, but it might not be worth reading due to some heavy language (for the non-physiologists reading).
The comparison of humans to turtles, who are capable of extraordinary longevity, perpetual sexual fecundity and virility, and looking totally awesome, was enough to merit reblogging, but this quote, referred to by Musicbrain and from the linked article, is amazing as well:
In a different study done in a more naturalistic setting on a different adept, Yogi Satyamurti (70 yr of age) remained confined in a small underground pit, sealed from the top, for 8 days. He was physically restricted by recording wires, during which time electrocardiogram (ECG) results showed his heart rate to be below the measurable sensitivity of the recording instruments…
Anything that gets me closer to being a turtle is crucially important.
