釋禪波羅蜜次第法門 9.18

9.18

復次，九想有二種：一者、利根；二者、鈍根。若利根之人，懸心存想死脹等事，悉得成就。若鈍根之人，懸作不成，必須見人初死至尸，所取是相已，繫心修習。既見相分明，心想成就，即發三昧，於後雖離死尸，隨想即見。

Furthermore, the nine notions have two kinds [of practitioners]: first, those of sharp faculties; second, those of dull faculties. If it is a person of sharp faculties, mentally conceptualizing in advance the matters of death, distension, and so on, all are accomplished. If it is a person of dull faculties, conceptualizing in advance is not accomplished; one must see a newly deceased person at the place of the corpse, and having seized these marks, tie the mind to cultivating and practicing. Once the marks are seen clearly and the mental notion is accomplished, samādhi is immediately generated; afterward, even though separated from the corpse, according to the notion one immediately sees it.
