Gongyo is the reality of the Trikaya or the Three Bodies of the Buddha in one. The recitation of the Hoben-pon is the body of the historical [Manifestation] Buddha specifically and our manifestations generally. The recitation of the Jiga-ge is the Reward Body of the Buddha or the Buddha's eternal wisdom and compassion [specifically] and ours generally. The recitation of the Daimoku is the Dharma Body. The Three Bodies do not exist as separate aspects of reality. They only have meaning as a unified whole.
