4.79

[Treatise:] if the mind has movement, it is not true knowing; [Commentary:] This contrastively reveals the meaning of illumining without inversion. The text here is brief; fully it should say: "If the mind has movement, it is not true knowing; the nature of the mind is free from movement, which is the meaning of real knowing." One opinion holds: this speaks of the characteristic of cognition and the characteristic of continuity, because these two defilements are coarse, moving minds that falsely generate conceptual discrimination of the pleasant and unpleasant, and so forth; therefore, they are not true knowing. Another opinion holds: this also speaks generally in contrast to all defilements. If the mind has movement, it is not true knowing, because the nine kinds of defiled mind are all movement. If there is no defiled moving mind of the nine kinds, this expresses the meaning of the true cognition of the mind's nature.
