俱舍論疏 28.175

28.175

「論曰至觸及發表」，述上地以無尋、伺，無三識身及發表心。借初定心，以五識身及發表心定與尋、伺相應故。

The passage of the śāstra from 'The Śāstra says' down to 'tangible and manifestative action' explains that the higher stages lack investigation (vitarka) and analysis (vicāra), and thus lack the three consciousness-bodies and the mind that produces manifestative action. They borrow the mind of the first dhyāna because the five consciousness-bodies and the mind that produces manifestative action necessarily associate with investigation and analysis.
