摩訶止觀 9.30

9.30

又就動觸空、明十種，論若過、若不及，此中之空，祇豁爾無礙，是為正空。若永寂絕，都無覺知者，太過；若鏗然塊礙，是不及。明者，如鏡月了亮，若如白日，或見種種光色，是太過；若都無所見，是不及。定者，祇一心澄靜，若縛著不動，是太過；若馳散萬境，此不及。乃至相應，亦如是。是為一動觸中二十種邪相；餘七觸合前，則有一百六十邪法。

Furthermore, in terms of the ten virtues of the touch of motion, such as emptiness and clarity, to discuss excess and deficiency: the emptiness here is merely open and unimpeded, which is proper emptiness. If it is permanently extinguished and silent, utterly devoid of awareness, that is an excess; if it is unyielding and obstructive, that is a deficiency. As for clarity, it is distinct and bright like the moon in a mirror; if it is like the bright sun, or one sees various lights and colors, that is an excess; if one sees nothing at all, that is a deficiency. As for concentration, it is simply a single mind settled and quiet; if one is bound and fixated without moving, that is an excess; if it gallops off distracted among myriad objects, that is a deficiency. And so on, down to correspondence, it is also like this. These are the twenty kinds of improper marks within a single touch of motion; combined with the other seven touches, there are altogether one hundred and sixty improper states.
