首楞嚴義疏注經 1.33

1.33

If explained together with "I heard", these are words pointing to the Dharma: "Such a Dharma as this I heard from the Buddha." The Treatise on the Buddha-Bhūmi says: "At the time of the compilation, the assembly jointly requested, saying: 'As you have heard, you should speak thus.' The Dharma-transmitting bodhisattva then assented, saying: 'Thus shall I speak, as I have heard.'" When explaining "thus" separately, it is the fulfillment of faith. The Mahāprajñāpāramitopadeśa says: "The great ocean of the Buddha's Dharma: faith is that which can enter it, wisdom is that which can ferry across. One with faith says: 'This matter is thus.' One without faith says: 'This matter is not thus.'" Master Zhao also says: "These are words of faith and compliance. When there is faith, the principle spoken is complied with; when complied with, the way of master and disciple is accomplished. Therefore, among the myriad practices, faith is primary; hence it says 'thus'." Furthermore, tallying with principle and tallying with capacity is called "thu-" (ru); eternally departing from errors and faults is called "-s" (shi). Spoken in accordance with principle and believed in accordance with principle, it therefore says "thus". If interpreted according to the present sūtra, the essential nature of the tathāgatagarbha mind being unmoving is called "ru"; being the true and real meaning, it is called "shi". Furthermore, all dharmas are originally free of arising and ceasing and are all the tathāgatagarbha, hence it is named "ru". Being free from all marks is immediately all dharmas, hence it is named "shi". There are yet other meanings, but they are too manifold to discuss.
