Yoga is not a religion, remember that. Yoga is not Hindu, it is not Mohammedan. Yoga is a pure science just like mathematics, physics or chemistry. Physics is not Christian, physics is not Buddhist. If Christians have discovered the laws of physics, then too physics is not Christian. It is just accidental that Christians have come to discover the laws of physics. But physics remains just a science. Yoga is a science – it is just an accident that Hindus discovered it. It is not Hindu. It is a pure mathematics of the inner being. So a Mohammedan can be a yogi, a Christian can be a yogi, a Jaina, a Buddhist can be a yogi.
Yoga is pure science. And Patanjali is the greatest name as far as the world of Yoga is concerned. This man is rare, there is no other name comparable to Patanjali. For the first time in the history of humanity this man brought religion to the status of a science. He made religion a science; pure laws, no belief is needed.
So-called religions need beliefs. There is no other difference between one religion and another; the difference is only of beliefs. A Mohammedan has certain beliefs, a Hindu certain others, a Christian certain others. The difference is of beliefs. Yoga has nothing as far as belief is concerned; Yoga doesn’t say to believe in anything. Yoga says “Experience.” Just as science says “Experiment,” Yoga says “Experience.” Experiment and experience are both the same; their directions are different. Experiment means there is something you can do outside; experience means there is something you can do inside. Experience is an inner experiment.
Science says, “Don’t believe, doubt as much as you can,” but also, Don’t disbelieve” – because disbelief is again a sort of belief. You can believe in God, you can believe in the concept of no-God. You can say God is with a fanatic attitude; you can say quite the reverse, that God is not, with the same fanaticism. Atheists, theists, are all believers, and belief is not the realm for science. Science means to experience something, that which is; no belief is needed.
So the second thing to remember is that Yoga is existential, experiential, experimental. No belief is required, no faith is needed – only courage to experience – and that’s what is lacking. You can believe easily because in belief you are not going to be transformed. Belief is something added to you, something superficial. Your being is not changed, you are not passing through some mutation. You may be a Hindu – you can become a Christian the next day. You simply change, you change the Gita for a Bible. You can change it for a Koran, but the man who was holding the Gita and is now holding the Bible remains the same. He has changed his beliefs.
Beliefs are like clothes. Nothing substantial is transformed, you remain the same. Dissect a Hindu, dissect a Mohammedan – inside they are the same. The Hindu goes to a temple, the Mohammedan hates the temple. The Mohammedan goes to the mosque and the Hindu hates the mosque but inside they are the same human beings.
