Manjushri, the bodhisattva of wisdom, the one who carries the double-edged sword that kills or gives life, asks a monk to bring him something out in the world that is not medicine. The monk searches far and wide, and finally returns, saying that there is nothing out there that is not medicine. To which the master says, “then bring me something that is medicine.” The monk then reaches down and plucks a blade of grass.

The master turns to the monk and says, “This medicine can kill people and it can also bring them to life.”
