When a man has understood the reason of all things and develops still further, then comes the realm of sympathy. Then naturally he has no blame for anybody, and that attitude culminates in harmlessness. Buddha says, "The essence of religion is harmlessness, and the moment you have become harmless, you have understood religion." What is harmlessness? People know so little about it. They think that being harmful means killing someone. But everyone has a meaning of his own for every word.
