For example, at the time when the Buddha was learning the path, he did not hesitate to offer his body to a starving lion. Or, if someone were to force a person in this room to jump off from the tenth floor, the behavior in the true sense of Mahayana would be that everyone in this room volunteers to jump. It is not just paying lip service. One should wish with all sincerity like this: It must be very painful to jump to death like that. Just let me take the pain for them.
