My dad went to a retreat for about 8 months where they weren't allowed to drink alcohol, had to hike for about 3 hours a day, exercised until they fainted, were screamed at, punched in the ribs and face if they didn't dress like everyone else, had to eat the same food every day, programmed to wipe their arse with one sheet, learned how to survive extreme conditions, instructed in the best way to eliminate a fellow Swami with their bare hands, and how to do it without anyone noticing. What that did to his Chakra is anyone's guess.
