摩訶止觀 3.42

3.42

巧度止有三種：一、體真止，二、方便隨緣止，三、息二邊分別止。一、體真止者，諸法從緣生，因緣空無主；息心達本源，故號為沙門。知因緣假合、幻化性虛，故名為「體」。攀緣妄想得空即息，空即是真，故言體「真止」。

Skillful-salvation calming has three kinds: first, calming of realizing the true; second, calming of conforming to conditions through expedients; third, calming of ceasing discrimination of the two extremes. First, the calming of realizing the true: all dharmas arise from conditions, and cause and conditions are empty and without master; ceasing the mind and reaching the fundamental source, one is therefore called a śramaṇa. Knowing that the provisional combination of causes and conditions is illusory and devoid of real nature is called 'realizing'. When discursive clinging and false thoughts obtain emptiness, they cease; emptiness is the true, and so it is called 'calming of realizing the true'.
