俱舍論疏 5.103

5.103

論「或即所依至假立為定」，第二釋也。即無心位所依色身假名為定。

Regarding the treatise's statement, "Or it is the support itself ... designated nominally as attainment": This is the second explanation. Namely, the physical body relied upon during the state of mindlessness is nominally designated as the attainment.
