Will power is nothing but another name of ego power. A man of wisdom has no will, just as he has no mind - because to will means to keep yourself separate from existence. It is a little subtle, but try to feel it. The moment you will it means you are always willing against things as they are. You want them to be some other way.
One of the names of Buddha is TATHAGATA - one who lives in suchness, one who has become free from all the distractions of the mind. And the miracle is that the mind consists only of distraction, so once you are free of all distractions there is no mind left. In the present there is no mind. In the present there is only consciousness, awareness, watchfulness.
Mind is a duality; it is always split. There is no single point on which the mind agrees in totality. Half of the mind will agree and half of the mind will disagree, and whatever you choose, you are choosing only the half. The remaining half is going to take revenge. The unchosen part, the left over, will wait for its chance to show you that whatever you have chosen is wrong. But it does not matter which part you choose. Choice itself is wrong.
