梵網經古迹記 1.80

1.80

述曰：第八、無相心中，「無相心」者，舉章門也。次明行相，謂亡相心照實相般若無二，復於一切煩惱業果如如一諦，亦行無生空，自知成佛，了平等故。佛是我性等者，賢聖是我行同者。結言「皆同無生空，故無相心」。

The commentary says: In the eighth, the signless mind, "the signless mind" introduces the chapter section. Next, clarifying the characteristic of practice: the mind that eliminates signs illuminates the non-duality of real-mark prajñā; furthermore, regarding all afflictions, karma, and results, they are such-like as a single truth, and one also practices non-arising emptiness, knowing oneself to become a Buddha because one comprehends equality. "The Buddha is my nature," etc., means that the worthies and sages are those whose practice is identical to mine. It concludes by stating, "All are identical in non-arising emptiness; therefore, it is the signless mind."
