According to Osho, all effort is a device to exhaust you: when the method is utterly used up and defeated, your ego breaks. In that weariness the 'doer' drops, and the no‑method prevails. Then, and only then, the happening—grace, awakening—occurs spontaneously; before that, as long as effort remains, it cannot happen.
When you try so hard that you finally give up, your pushy “I” drops, and then the truth happens by itself.
