摩訶止觀 5.162

5.162

信行安心者，或欲聞寂定如須彌不畏八動，即應聽止。欲聞利觀破諸煩惱如日除闇，即應聽觀。聽觀多，如日焦芽，即應聽止，潤以定水。或聽定淹久，如芽爛不生，即應聽觀，令風日發動使善法現前。或時馳覺，一念叵住，即應聽止，以治散心。或沈昏濛濛坐霧，即當聽觀，破此睡熟。或聽止豁豁，即專聽止；或聞觀朗朗，即專聽觀。是為自修信行八番巧安心也。

Regarding settling the mind for a practitioner of faith: if one wishes to hear about quiescent concentration, which like Mount Sumeru does not fear the eight movements, one should listen to calming. If one wishes to hear about sharp contemplation to break through all afflictions like the sun dispelling darkness, one should listen to contemplation. If one listens much to contemplation, it is like the sun scorching sprouts; one should immediately listen to calming, moistening them with the water of concentration. Or if one has been soaked in listening to concentration for long, like sprouts rotting and not growing, one should immediately listen to contemplation, letting wind and sun stir them into action so that good dharmas appear before one. Or when sensations race about and not a single thought-moment can abide, one should immediately listen to calming to remedy the distracted mind. Or if one sinks into dullness, enveloped as if sitting in mist, one should immediately listen to contemplation to break this heavy sleep. Or if through listening to calming one becomes open and clear, one should focus exclusively on listening to calming; or if through hearing contemplation one becomes bright and clear, one should focus exclusively on listening to contemplation. This is the eightfold skillful settling of the mind in self-cultivation for a practitioner of faith.
