法華義疏 9.20

9.20

開一為三凡有二種：一者、開一法為三法；二者、開一人為三人。上來雖明一法為三法、三法歸一法，未辨一人為三人、三人為一人。今發諸菩薩迹始得明一人為三人、三人為一人，以具約人法明於開會，義始圓也。

Opening the one into three has generally two types: first, opening the one Dharma into three Dharmas; second, opening the one person into three persons. Although above it has been explained that the one Dharma becomes three Dharmas and the three Dharmas return to the one Dharma, it has not yet distinguished that the one person becomes three persons and the three persons become one person. Now, by revealing the origins of the bodhisattvas, it only now becomes possible to clarify that the one person becomes three persons and the three persons become one person. Because the opening and converging are explained comprehensively with respect to both persons and Dharmas, the meaning only now becomes complete.
