觀音玄義記 3.17

3.17

問：四十二位，自等覺來合判為僧，妙覺為佛。云何因果皆名為僧？答：別相三寶乃以因果而為僧佛。今論一體，一人一念具足三寶。四十二位，位位報智冥於法性，皆名二寶。位位應身，皆名僧寶。故妙覺應最能三土統理大眾，是故僧寶究竟成就。若能善識一體三寶，任運能具諸漸教中三寶之義，以能和於理事三諦故也。

Question: In the forty-two stages, from equal enlightenment downward they should be judged as the Saṅgha, and marvelous enlightenment as the Buddha. Why are both cause and effect called the Saṅgha? Answer: The three jewels of distinct marks indeed take cause and effect as Saṅgha and Buddha. But now we are discussing the single substance, where one person in a single thought completely possesses the three jewels. In the forty-two stages, at every stage the reward-wisdom is unified with dharmatā, both of which are called the two jewels [of Buddha and Dharma]. At every stage, the responsive body is called the Saṅgha jewel. Therefore, the responsive [body] of marvelous enlightenment is most able to govern the great assembly across the three lands; hence the Saṅgha jewel is completely perfected. If one can properly understand the three jewels of the single substance, they will naturally possess the meaning of the three jewels within the various gradual teachings, because they can harmonize with principle, phenomena, and the three truths.
