Slowly and gradually you get into the chambers of the mind and gradually get control of the mind. It is a long, [hard struggle]. It must not be taken up as something curious. When one wants to do something, he has a plan. [Raja-Yoga] proposes no faith, no belief, no God. If you believe in two thousand gods, you can try that. Why not? ... [But in Raja-Yoga] it is impersonal principles.
