俱舍論疏 2.192

2.192

論「謂無間生」，答也。非是相觸名至，但無間生名至，一切功能不離體故，不可言體不至、功能至也。三根知境雖近遠不同，俱無間生，皆名為至。

On the Śāstra's statement: "It means arising without interval": this is the answer. It is not that mutual contact is called contiguous; rather, merely arising without interval is called contiguous. Since all functioning is inseparable from substance, one cannot say that the substance is not contiguous while the functioning is contiguous. Although the three sense-faculties' cognition of their objects differs in proximity and distance, they all arise without interval, and all are called contiguous.
