He was astonished to see Chen put away plate after plate after plate of food.

Chen read his mind and told him …

“I don’t shit. I turn it all into Qi.”

“‘With all your strength’ is your breath. Oxygen induces rhythm, vital movement, timing. One atom of oxygen could last you forty years. Live by intracellular osmosis.”

“In 2010, a team from the Indian Defense Institute of Physiology and Allied Science (DIPAS) investigated an eighty-three-year-old yogi called Prahlad Jani, who lived in the temple town of Anbaji in Gujarat. His devotees claimed that he had not eaten for seventy years. In the DIPAS study, he was kept for two weeks in a hospital under continuous observation and filmed on CCTV cameras. He had several baths and gargled, but the medical team confirmed that he ate and drank nothing, and passed no urine or feces. A previous medical investigation in 2003 had given similar results. The director of DIPAS said, ‘If a person starts fasting, there will be some changes in his metabolism but in his case we did not find any.’ This is an important point, because surviving a two-week fast is in itself not particularly impressive. Most people could do that, but there would be very noticeable physiological changes while they did so.”
