In conversation with His Divine Grace A. C. Bhaktivedānta Swami Prabhupāda
Young man: What do you think of kundalini or rāja-yoga?
Prabhupāda: We are practicing the emperor yoga. Therefore rāja-yoga is included there. The Bhagavad-gita says that,
Anyone who is always thinking of Krishna within himself, he is the topmost yogi. Therefore a person who is in Krishna consciousness on the authority of Vedic literature, he is supposed to have surpassed all kinds of yogic principles. What is your understanding of kundalini yoga? Do you know?
Young man: It’s very dangerous.
Prabhupāda: So why do you accept such a dangerous thing?
Young man: No, I just wanted to know what you thought of it.
Prabhupāda: There is no need of… It is not possible to practice that yoga. The kundalini process of yoga is not possible in this age. It is a very difficult process. So we should recommend not to waste your valuable time following something which is not possible to be done by you. That is our recommendation. But if you have got some hobby, that is a different thing. But it will never be successful. It is very difficult to perform. At the present age, as it is recommended and it is followed, practiced, and experienced, this bhakti-yoga is the only possible way for self-realization. It is made very simple: simply chanting
Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare
Hare Rāma, Hare Rāma, Rāma Rāma Hare Hare.
Anyone can do it. In any part of the world can people practice it. Of any age, it doesn’t matter, either old, young, or child. We have got many children of our devotees, they are also chanting Hare Krishna. And many old men like me, they are also chanting Hare Krishna. And these young boys and girls, they are also chanting Hare Krishna. So it is universal. And these boys and girls are neither Hindus nor Indians, nor do they have any knowledge of Sanskrit. But they easily pick up this Hare Krishna and chant and are getting the result. So this is the easiest, universal method of self-realization in the present age. Any other practice of yoga system will never be successful. It will be simply waste of time.
