There are disciplines such as Hatha Yoga and Raja Yoga that one can practice and yet have nothing to do with the spiritual life; the former arrives mostly at body control, the latter at mind control. But to enter the spiritual life means to take a plunge into the Divine, as you would jump into the sea. And that is not the end but the very beginning; for after you have taken the plunge, you must learn to live in the Divine. How are you to do it? You have simply to jump straight in and not to think: "Where shall I fall? What will happen to me?" It is the hesitation of your mind that prevents you. You must simply let yourself go. If you wish to dive into the sea and are thinking all the time: "Ah, but there may be a stone here or a stone there," you cannot dive.
…Take the whole and entire plunge and you will be free from this outer confusion and get the true experience of the spiritual life.
