大乘義章 8.24

8.24

次就諸地分別識住。地謂九地，始從欲界乃至悲想。若依《毘曇》，要當地法望當地識說為識住，異地則非，麁細別故。若如是者，依下地身起上心時，下地之身應非識住。論自釋言「住相成就，猶名識住。」若依《成實》，莫問自地及與他地，但有緣著，斯名識住（此三門竟）。

Next is the differentiation of the abodes of consciousness in terms of the various planes. The planes refer to the nine planes, starting from the desire realm up to [the peak of existence, the plane of neither] perception [nor non-perception]. According to the Abhidharma, it is necessary that dharmas of that plane be spoken of as abodes of consciousness with respect to consciousness of that plane; different planes are not so, because of the distinction between coarse and subtle. If that is so, when one relies on a body of a lower plane to generate a mind of an upper plane, the body of the lower plane should not be an abode of consciousness. The treatise itself explains: 'Because the characteristic of abiding is accomplished, it is still called an abode of consciousness.' According to the Tattvasiddhi, without asking whether it is one's own plane or another plane, as long as there is an object-grasping attachment, this is called an abode of consciousness (this concludes the third section).
