What do you want to do sadhana for? The aim should not be the satisfaction of egoism: "I want to be a great yogi; I shall have so much power and with that power I shall establish myself in the world." All such thoughts must be thrown far away.
So I analyzed that and decided I didn't want to be the president during a depression greater than the Great Depression, or the beginning of a depression greater than the Great Depression.
One thing I want to make clear, as far as my own rebirth is concerned, the final authority is myself and no one else, and obviously not China's Communists.
