There was a story in the Vinaya: A bihkshu who was rendered immobile due to his illness had no one to take care of him. His bed was so filthy that it was as if he slept in his own excrement. One day, the Buddha came to this bihkshu’s home with Ananda. The bhikshu panicked upon seeing the Buddha, but the Buddha gently comforted him and took his dirty clothes to wash personally.

If the Buddha could do this, we the followers of the Buddha would have no excuse not to do likewise. Yet, this is still not quite real compassion. Real compassion means that, at the time of life and death, one chooses to sacrifice one’s own life for others. Although this ideal may also exist in some other schools of thought or theory, it is somewhat limited in their scope. Whereas the Buddha’s great compassion is for all sentient beings, not just humans or Buddhists.
