Before dealing with the Four Noble Truths, Buddhism teaches the everyday common-sense law that a good cause produces a good effect, a bad cause a bad effect; and both kinds of causes, suitable rewards and retributions. Even small acts of good and small acts of evil unrelated to other acts of good and evil do not disappear without a trace. Instead, each is stored up to form the intellect, personality, customary behavior, and physical makeup of the individual committing them. They become part of the personality, which they daily alter in the direction of good or bad. Acts of good and evil are intimately related to the individual’s happiness and fate. All human beings must understand that everything in this world is related according to the inflexible law of cause and effect. (Page 95)
