成唯識論述記 6.52

6.52

述曰：第二師。所樂者，謂所求之境，隨境體性可欣，可厭，但求於彼可欣事上，未得望合，已得願不離；可厭之事，未得願不得，合已得願別離中，皆得起欲。故論但言：「求合離等」，等取彼也，即緣此二皆得生欲，餘文可解。故體寬於第一，唯前七識，或唯第六有此欲故。於中，容境全不起欲，即通八識，或唯前六及八，以第七識常希求故。

The Commentary states: The second master. "Desired" means a sphere that is sought; whether the sphere's intrinsic nature is delightful or loathsome, as long as on that delightful thing, when not yet attained one hopes to unite with it, and when already attained one wishes not to be separated from it; and on a loathsome thing, when not yet attained one wishes not to encounter it, and having encountered it one wishes to be separated from it—in all these desire can arise. Thus the treatise merely says: "seeking union, separation, etc.," where "etc." includes those; namely, by taking both of these as cognitive objects, desire can arise; the rest of the text can be understood. Therefore its scope is broader than the first, and only the first seven consciousnesses or only the sixth have this desire. Toward neutral spheres, desire does not arise at all; this pertains to all eight consciousnesses, or only the first six and the eighth, because the seventh consciousness is constantly seeking.
