The Practice of Odaimoku Chanting

All the merits Śākyamuni Buddha has attained, in other words, his true heart, are included in the Five Letters of myō-hō-ren-ge-kyō. If we believe in and practice the teachings of the Five Letters at the cost of our lives, we are able gradually but surely to gain the Buddha’s true heart.
