修習止觀坐禪法要 1.110

1.110

三、坐者。若於坐時，應作是念：「我今為何等事欲坐？若為諸煩惱及不善無記事等，即不應坐。為善利益事，則應坐。」云何坐中修止？若於坐時，則當了知因於坐故，則有一切煩惱善惡等法，而無一法可得，則妄念不生，是名修止。云何坐中修觀？應作是念：「由心所念，壘脚安身，因此則有一切善惡等法，故名為坐。」反觀坐心，不見相貌。當知坐者及坐中一切法，畢竟空寂，是名修觀。

Third, sitting: When sitting, one should think thus: "For what matter do I wish to sit now? If for defilements, unwholesome or indeterminate matters, and so forth, I ought not to sit. If for matters of wholesome benefit, I ought to sit." How does one cultivate calming while sitting? When sitting, one should thoroughly know that because of sitting, there are all defilements, wholesome, unwholesome, and other phenomena, yet not a single phenomenon can be grasped; deluded thoughts then do not arise. This is called cultivating calming. How does one cultivate contemplation while sitting? One should think thus: "Through the ideation of the mind, folding the legs and settling the body, because of this there are all wholesome, unwholesome, and other phenomena; therefore it is termed sitting." Reflexively contemplating the mind that sits, one sees no appearance [of it]. One should know that the sitter and all phenomena within sitting are ultimately empty and tranquil. This is called cultivating contemplation.
