說無垢稱經疏 1.22

1.22

As for the words "I have heard," the bodhisattva transmitting the Dharma points to his own person and says: "Such Dharma I personally heard from the Buddha." Therefore it is called "I have heard." "I" refers to the aggregates, a conventional imputation. However, there are three kinds of "I": first, the erroneously grasped "I," referring to the "I" falsely conceptualized by non-Buddhists and the like; second, the nominally designated "I," referring to the "I" of the bliss, purity, and permanence of the Great Nirvāṇa, forcibly designated in order to eliminate the inversions of the two vehicles; third, the conventionally circulating "I," referring to names commonly transmitted in the world such as Devadatta. Now the transmitter of the Dharma accords with the world and points to himself by speaking of "I"; it is not the same as the former two, but is the "Great Self" of selflessness.
