The Body, Voice and Heart of the Eternal Buddha

[T]ue Lotus Sutra, the Odaimoku and the Mandala Gohonzon represent the very body, voice and heart of the Eternal Buddha. We should therefore strive to clearly pronounce the Odaimoku as we chant it. Concentrate on each syllable and observe the Odaimoku written on the Mandala Gohonzon. While chanting serenely and solemnly from deep within our diaphragm, our voice should be neither too loud nor too soft. Maintain a melodic rhythm, neither too fast nor too slow.
