大乘起信論別記 1.22

1.22

Question: In the gate of tathatā only the meaning of emptiness is expounded, and within the gate of arising and ceasing the meaning of non-emptiness is expounded—is it not so? Answer: Correlating them superficially, this meaning is not absent; hence in the preceding section establishing the meaning, within the characteristics of tathatā, it only says that it can show the essence of the Mahāyāna, while in the gate of arising and ceasing, it also says that it shows the characteristics and function of the Mahāyāna. If speaking according to the real truth, however, it is not so. Therefore, in the subsequent text of the treatise, both gates expound the meaning of non-emptiness.
