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.
Today I am in control because I want to be. I have my fingers on the switch, but have lived a lifetime ignoring the control I have over my own world. Today is different.
The world is not something separate from you and me; the world, society, is the relationship that we establish or seek to establish between each other. So you and I are the problem, and not the world, because the world is the projection of ourselves, and to understand the world we must understand ourselves. That world is not separate from us; we are the world, and our problems are the world's problems.
...mysticism and empiricism go together in opposition to scholasticism...they base themselves on the non-linear world of experience rather than the linear world of letters.
