摩訶止觀 5.250

5.250

佛弟子觀無生，若發空心，空心生時即知是愛，何者？生名愛法，愛法即是無明，無明生我見等八十八使，一一皆具三假之惑，終不執謂是真無生。云何三假？良由上來有見三假被伏，度入無見。無生法塵對意根，一念空心生，即因成假；以生心滅故，無生心生，是相續假；豁爾無生待於有生，是相待假。

When a disciple of the Buddha contemplates non-arising, if a mind of emptiness arises, at the very moment the mind of emptiness arises they immediately recognize it as craving. Why? Arising is called a dharmic factor of craving, and a dharmic factor of craving is avidyā; avidyā gives rise to the eighty-eight proclivities such as the view of self, each of which possesses the delusions of the three provisionalities, and so they never cling to it, claiming it is true non-arising. What are the three provisionalities? Because previously the three provisionalities of the view of existence were subdued, one passes over into the view of non-existence. When the mental object of non-arising faces the mind-sense, a single thought-moment of a mind of emptiness arises: this is the provisionality of conditioned arising. Because the mind of arising has ceased, the mind of non-arising arises: this is the provisionality of continuity. The sudden non-arising relies upon the existence of arising: this is the provisionality of relativity.
