Buddhas can take you to the boundary line of meditation and samadhi. That is the only difference between meditation and samadhi. If your mind has become utterly quiet and silent, but only the master is there, then it is meditation. If your mind has become so quiet that even the master has disappeared, it is samadhi. The last barrier is going to be the master. He will take you out of the world, but one day you will have to leave him too. And the real master will always keep you alert that you have to leave him one day, at the final stage.
RajneeshZen is not effort. Effort is tension, effort is work, effort is to achieve something. Zen is not something to achieve. You are already that. Just relax, relax so deeply that you become a revelation to yourself.
RajneeshOrdinarily, even when people become religious, they go on thinking in terms of having - possessing heaven or possessing the pleasures of heaven - but still they go on thinking in terms of having. Their heaven is nothing but their projected desire of having everything. All that they have missed here they would like to have in the after-life. But it is the same desire.
