2.251

The Bodhisattva Sunakṣatra said, "This movement and this thought constitute duality. If there is no movement, there is no thought; if there is no thought, there is no discrimination. One who thoroughly penetrates this enters the dharma gate of non-duality."
Sengzhao says, "The stirring of emotion is movement; the forming of conceptualization is thought." Another explanation says, "Peacefully abiding in the true nature means that nature has no movement; no movement means no thought."
