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.
For if you know what you want, and will be content with it, you can be trusted. But if you do not know, your desires are limitless and no one can tell how to deal with you. Nothing satisfies an individual incapable of enjoyment.
You want accuracy, but not representation. If you know how to make the figuration, it doesn't work. Anything you can make, you make by accident. In painting, you have to know what you do, not how, when you do it.
I have enough of life in me to make somebody jealous enough to want to knock me down. I have so much courage in me that I have the effrontery, the incredible gall to stand up. That's it. That's how you get to know who you are.
