Compassion is not feeling -- because feeling has many things in it which are not in compassion at all. Feeling has sentimentality, emotionality -- those things don't exist in compassion. The man of compassion feels, but without any emotion. He feels, but there is no sentimentality. He will do whatsoever is needed, yet he remains untouched by it. This has to be understood very deeply. And once you understand compassion, you have understood what a Buddha is.
