Whai is cause and effect?

The Daishonin explains the significance of cause and effect: All sutras other than the Lotus Sutra expound that Buddhahood (effect), can be attained only after having made good causes, that is, practicing their teachings (causes), over a length of time. With the Lotus Sutra, however, the very act of embracing it (cause) enables one simultaneously to become a Buddha (effect).

Good causes and good effects

Just as flowers open up and bear fruit, just as the moon appears and invariably grows full, just as a lamp becomes brighter when oil is added, and just as plants and trees flourish with rain, so will human beings never fail to prosper when they make good causes. -Nichiren
