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.
There are times when you don't know yourself. There are times when you don't want to know yourself. There are times when you want to be what you have never allowed yourself to be before.
The older I get, the more I realize that you don't have to be around people you don't want to be around, and you don't have to be in a situation you don't want to be in. You have the power to rise up and leave.
