"Of course it is going to be hard work; it is not just poetry and dreaming. A man has to become a lab, a man has to transform his whole life into an experiment – only then can the truth be realized.

"So while listening to Patanjali's sutras never forget it, that he is not handing you some theories, he is giving you a methodology that can transform you. But then it depends on you.

"There are four types of people who become interested in religion. The first, the majority, is only curious, is in search of something amusing, something outlandish, something interesting, something fascinating. Patanjali is not for those, because a curious person is never so deeply interested that he can be convinced to transform his life. He is looking for a sensation. Patanjali is not for those people.

"Then there is a second type we will call the student. He is interested intellectually; he would like to know what this man Patanjali is thinking, saying – but he is interested in knowledge. Not in knowing, but knowledge. He is interested in gathering more information. He is not ready to change himself; he would like to remain himself and gather more knowledge. He is on an ego trip. Patanjali is not for that type either.

"Then there is the third type, the disciple. A disciple is one who is ready to discipline his life, who is ready to transform his whole being in an experiment, who is courageous enough to go on this inner adventure – which is the greatest, which is the most daring, because nobody knows where one is moving. One is moving into the unknowable. One is moving into the abyss. One is moving into the uncharted. Yoga is for the disciple; the disciple will be able to get in tune with Patanjali.

"Then there is the fourth state, or the fourth type; I will call it the devotee. The disciple is ready to change himself, but still not ready to sacrifice himself. The devotee is ready to sacrifice himself. The disciple will go far enough with Patanjali, but not to the very end, unless he becomes a devotee also, unless he comes to recognize that the transformation that religion is concerned about is not a modification."
