摩訶止觀 5.19

5.19

不次亦三義，謂：法、修、發。發則不定，或前發菩薩境，後發陰入。雖不次第，十數宛足。修者，若四大違返則先修病患；若四分增多則先修煩惱。如是一一隨強者先修。法者，眼、耳、鼻、舌，陰、入、界等，皆是寂靜門，亦是法界，何須捨此就彼？出《寶篋經》（云云）。當知法界外，更無復有法而為次第也。

Non-sequential also has three meanings: phenomena, cultivation, and arising. Arising is indeterminate; the bodhisattva realm may arise first and the aggregates and sense fields later. Although not sequential, the tally of ten is fully complete. Cultivation means: if the four great elements are in conflict, one cultivates [the contemplation of] illness first; if the four modes increase, one cultivates [the contemplation of] afflictions first. In this way, one cultivates whatever is predominant first. Phenomena means: the eyes, ears, nose, tongue, aggregates, sense fields, realms, and so forth are all gates of serenity and are themselves the dharmadhātu; why should one abandon this to take up that? This is drawn from the Ratnakāraṇḍa-sūtra, and so forth. One should know that outside the dharmadhātu, there are no other phenomena whatsoever to constitute a sequence.
