The sun shines equally on diamond and charcoal, but the former has developed qualities that enable it to reflect the sunlight brilliantly, while the latter is unable to reflect the sunlight. Emulate the diamond in your dealings with people. Brightly reflect the light of God's love.
Paramahansa YoganandaThe universal law of karma ... is that of action and reaction, cause and effect, sowing and reaping. In the course of natural righteousness, man, by his thoughts and actions, becomes the arbiter of his destiny.
