俱舍論疏 8.110

8.110

論「謂彼所繫至是名識住」，此答所住法也。謂欲、色界繫，五蘊為所住。三無色中，四蘊為識住。此中說識於處想樂住，故兼取識也。非如四識住，唯四蘊也。

The verse commentary states: "Namely, bound to that [...] are called stations of consciousness." This answers regarding the dharmas in which it abides. Namely, for those bound to the desire and form realms, the five skandhas are what it abides in. In the three formless realms, the four skandhas are the stations of consciousness. Here, it is said that consciousness desires and delights in abiding in these places, so it also includes consciousness itself. It is not like the four stations of consciousness, which are only four skandhas.
