Morality in human relation means … a life of gratitude shown in fidelity to the Lord, obedience toward one’s master, and filial piety toward one’s parents; all other moral relations flow out of these fundamental ones. But this passive aspect of morality implies the active duty of showing gratitude by perpetuating the will of the benefactor. The ruled fulfills his duty by cooperating with the ruler in the maintenance of order and government, the disciple by propagating the truth taught by the master, and the child by perpetuating the life given by his parents. Similarly, with moral duties viewed from the standpoint of religion: the true faith consists in propagating the Truth, and in ourselves living the life of Truth as revealed by Buddha. This is what is inculcated in the [Lotus Sutra] and is the real import of the vows taken by the saints, the faithful disciples of Buddha.
