Compassion comes by the thought, "I cannot expect of a person what he is unable to think or do as I expect it of him." It [that expectaton] is simply like this, to feel that the pear tree must give roses, and the rose tree must give jasmine. Every person is a certain plant, not the same plant. Yes, we may be fond of roses, but every plant does not give roses. If we want roses we must only seek the rose plant. If it is not the rose plant, we must not be disappointed that it is not the rose plant. The plant that does not give roses is not the rose plant. In this way we can correct ourselves of our own disappointment, instead of demanding roses of a tree which is not a rose tree.
