Buddhism teaches that life at each moment embraces all phenomena. This is the doctrine of a life-moment possessing three thousand realms, which is the Lotus Sutra’s ultimate teaching and Buddhism’s essence. Because of the profound way our lives interact with people around us, it is vital that we reach out to others, that we be engaged with our environment and with our local community. A self-absorbed practice or theory without action is definitely not Buddhism.
