成唯識論掌中樞要 2.149

2.149

有義：三地就二前、後相應建立，謂欲界地及初靜慮麁心、心所，前、後相續可有尋、伺共相應故，名有尋有伺地。靜慮中間麁心、心所前、後相續，定無有尋，唯可有伺共相應故，名無尋唯伺地。第二靜慮以上諸地諸心、心所前、後相續決定不與尋、伺相應，名無尋無伺地。若欲界地及初靜慮、靜慮中間細心、心所不與尋、伺共相應者，及一切色、不相應行、諸無為法不與尋、伺共相應故，亦皆說名無尋無伺地。故後論言有尋有伺地、無尋唯伺地一向是有心地。無心睡眠、無心悶絕、無想定、無想生、滅盡定及無餘依涅槃界並名無心地。

There is an opinion: The three levels are established with respect to mutual association of the two before and after. That is, coarse minds and mental factors of the desire realm and the first dhyāna, because their continuity before and after can be associated together with both investigation and analysis, are called the level with investigation and with analysis. In the intermediate dhyāna, coarse minds and mental factors in their continuity before and after definitely lack investigation and can only be associated together with analysis; hence it is called the level without investigation and with analysis only. From the second dhyāna upward, minds and mental factors in their continuity before and after are decisively not associated with investigation and analysis; hence it is called the level without investigation and without analysis. If subtle minds and mental factors in the desire realm, the first dhyāna, and the intermediate dhyāna are not associated with investigation and analysis, and because all forms, non-concurrent formations, and unconditioned dharmas are not associated with investigation and analysis, they are also all called the level without investigation and without analysis. Therefore, the subsequent treatise states that the level with investigation and with analysis and the level without investigation and with analysis only are exclusively levels with mind. Mindless sleep, mindless fainting, the absorption without conceptualization, birth without conceptualization, the absorption of cessation, and the nirvāṇa-realm without remainder are all called levels without mind.
