1.13

「正覺海」下，第二明所敬之尊極。問：何以知此是一體三寶？答：既稱淨法無為僧，即知是明常住僧。在僧既爾，法佛例然。問：何故敬一體三寶耶？答：既是一乘究竟之經，必明究竟三寶。又以究竟三寶顯知一乘，一乘是圓極之經，仍用此言斥北土四宗之說、江南五時之教也。

From "ocean of perfect awakening" downward is the second, clarifying the supreme culmination of the object venerated. Question: How is it known that this is the Three Jewels of identical substance? Answer: Since it refers to the "unconditioned Saṃgha of pure dharma," one knows that this clarifies the permanently abiding Saṃgha. Since it is so for the Saṃgha, the Dharma and the Buddha follow the same pattern. Question: Why venerate the Three Jewels of identical substance? Answer: Since this is the ultimate sūtra of the ekayāna, it must clarify the ultimate Three Jewels. Furthermore, by means of the ultimate Three Jewels, it makes known the ekayāna; the ekayāna is the consummate and ultimate sūtra. This statement is also used to refute the theory of the four tenets of the Northern Lands and the teaching of the five periods of the South of the River.
