What I like about Buddhism is its corrosive aspect. It destroys itself. As a famous great Dzogchen master said. He said something like practicing spiritual path should be like sharpening knife. When you sharp knife, two exhaustions happen. Exhaustion of the whetstone and exhaustion of a metal. And this exhaustion is called sharp knife. On the one hand we have emotions to deal with. The antidote to this emotion is the love and compassion and all the meditation and discipline and so on and so forth. But they also have to exhaust.
