大乘起信論義記 2.63

2.63

In the extensive explanation, although grasping and attachment are manifold, they do not exceed these two sets of four propositions. Thus the Śataśāstravipula says: "Furthermore, to reveal that all phenomena grasped by the world are unreal, and to reveal the differences among what is grasped by non-Buddhists, the verse says: 'Existence, non-existence, both, and neither; / unity, non-unity, both eliminated; / matched accordingly in order, / the wise understand they are unreal.'" That treatise extensively refutes the positions of the four schools of non-Buddhists in sequence, fully as explained there; in the present treatise, these propositions are formulated based on the shifting assumptions of outsiders, and thus differ from that text.
