仁王般若經疏 2.131

2.131

"Great King! That which is existent or non-existent is conventional truth. Since all dharmas are subsumed under three truths—the truth of emptiness, the truth of form, and the truth of mind—I therefore say that all dharmas do not go beyond the three truths. The views and knowledge of self and person, and the five grasping aggregates, are empty, up to all dharmas being empty. Sentient beings vary in classes, faculties, and practices; therefore the Dharma-doors are neither one nor two."
