首楞嚴義疏注經 8.548

8.548

不依正覺者，三乘行法皆佛所教，今經尚斥二乘，云不識生死根本，錯亂修習，況修仙道耶！存想固形者，存心在於長生不死，俾此形骸堅固不壞也。別修妄念，即下十種修鍊之法也。此皆有漏，進不如天、退又勝人，故居山林人不及處，名為仙趣。然此一趣餘經不出，以總報同人故。今經開者，約所修行別故，人、天二趣所不攝故，此皆外道類收。然亦禁防非佛正戒，但禁麁浮，即戒禁取也。

'Not relying on proper awakening': the practices of the three vehicles are all taught by the Buddha; the present sūtra still reproves the two vehicles, saying they do not recognize the root of birth and death and cultivate mistakenly—how much more so for cultivating the way of immortals! 'Sustaining ideation to solidify the physical form': keeping their minds fixed on long life and immortality, causing this bodily frame to be firm and imperishable. 'Cultivating distinct false thoughts' refers to the ten kinds of practices of refining below. These are all tainted [practices]; advancing, they are inferior to the devas; retreating, they are superior to humans; hence they dwell in mountains and forests where humans do not reach, and are named the destiny of immortals. Yet this destiny does not appear in other sūtras, because their shared collective retribution is the same as humans. That the present sūtra opens it up is because their cultivated practices are distinct, and they are not subsumed under the two destinies of humans and devas; these are all included among the categories of non-Buddhists. However, their prohibitions are not the Buddha's true precepts; they merely restrain coarse levity, which is clinging to rules and rituals (śīlavrata-parāmarśa).
