首楞嚴義疏注經 3.47

3.47

The tongue faculty not moving analogizes the true nature, the lips analogize avidyā, and licking analogizes the conjunction of the true and the false. Fatigue is the movement of thought; because thought moves, realms arise, such as sweet, bitter, and bland. Question: Sweetness and bitterness arise due to fatigue, and thus can analogize delusive realms. Blandness is the tongue faculty not moving and ought to analogize the real; why does it analogize a realm? Answer: Originally not moving can analogize the real; now, because it is revealed as not moving by means of movement, since it is a matter of relative contrast, it constitutes delusion. As it says below: "Speaking of delusion reveals the real; delusion and reality are equally two delusions." The rest is as in the text.
