Just as treasures are uncovered from the earth, so virtue appears from good deeds, and wisdom appears from a pure and peaceful mind. To walk safely through the maze of human life, one needs the light of wisdom and the guidance of virtue.
Since we desire the true happiness that is brought about by a calm mind, and such peace of mind arises only from having a compassionate attitude, we need to make a concerted effort to develop compassion.
I encourage courtesy. To accept nothing less than courtesy, and to give nothing less than courtesy. If we accept being talked to any kind of a way, then we are telling ourselves we are not quite worth the best. And if we have the effrontery to talk to anybody with less than courtesy, we tell ourselves and the world we are not very intelligent.
