In April 1970 Osho introduces a revolutionary cathartic meditation technique, which he calls Dynamic Meditation.

There are two ways: either relax directly as Tao implies, or relax indirectly as the Upanishads say. Create the tension to its ultimate, and then there will be relaxation. And I think the Upanishads are more helpful, because we are tense and we understand the meaning, the language, the ways of tension. Tell someone suddenly to relax and he cannot….

I was working for ten years continuously with Taoist methods, so I was continuously teaching direct relaxation. It was simple for me so I thought it would be simple for everyone. Then, by and by, I became aware that it is impossible. I was in a fallacy: it was not possible. I would say, “Relax!” to those I was teaching. They would appear to understand the meaning of the word, but they could not relax. Then I had to devise new methods for meditation which create tension first—more tension. They create such tension that you become just mad. And then I say, “Relax.”

When you have come up to the climax, your whole body, your whole mind, becomes hungry for relaxation. With so much tension, you want to stop, and I go on pushing you to continue, continue to the very end. Do whatsoever you can do to create tensions, and then, when you stop you just fall down from the peak into a deep abyss. The abyss is the end, the effortlessness is the end, but the Upanishads use tension as the means. ultas107
