TRINITY

For the Blessed One possesses three personalities and each of them is of equal importance to us. There is the Dharma Kaya. There is the Nirmana Kaya. There is the Sambhoga Kaya.

Buddha is the all-excellent truth, eternal, omnipresent, and immutable: this is the Sambhoga Kaya which is in a state of perfect bliss.

The truth is not arbitrary nor a matter of opinion, but can be investigated, and he who earnestly searches for the truth will find it. The truth is hidden to the blind, but he who has the mental eye sees the truth. The truth is Buddha’s essence, and the truth will remain the ultimate standard. Let us, then, revere the truth; let us inquire into the truth and state it, and let us obey the truth. For the truth is Buddha our Master, our Teacher.

Buddha is the all-loving teacher assuming the shape of the beings whom he teaches: this is the Nirmana Kaya, his apparitional body.

Buddha is the all-blessed dispensation of religion; he is the spirit of the Sangha and the meaning of the commands left us in his sacred word, the Dharma: this is the Dharma Kaya, the body of the most excellent law.
