I 'seem' to recall [back in B&W TV days] Krishnamurti was on some 'interview' show [David Suskind?] with a holy man from India. Km described the fasting of such holy men, as to limit their intake so much, they had the ability to 'recycle' their own urine.
The host was incredulous. Km spoke to the other robed man and handed him a glass.
Glass went under the robe, came out with something clear in it and the holy man drank the contents.
Obviously the man didn't eat hamburgers at the local greasy spoon, not would I be willing to bet - did he drink 'Animal beer'.
Those were the days, my friend......B-)
