I mentioned Bodhichtitta, because thinking about the willpower of Christ, I cannot think of anything else.
So you mean willpower can also be negative? Like coming from the Ego? And if it is true, shouldn't we just get even more our own willpower to do meditate and understand our selves?
Will is dual. It can be selfless (Christic) or selfish (desire, ego).
We cultivate either based on our actions in the moment. It is best to renounce egotistical will for the sake of superior action, since the later transforms us beneficially whereas the former does not.
