9.594

述曰：前相見道安立諦有二種十六心，今法於彼名二十六種。法彼二箇十六種，止、觀二心別立。

The Commentary states: In the preceding figurative path of seeing of posited truths, there are two kinds of sixteen moments of mind; now, modeling those, they are called twenty-six kinds. Modeling those two sets of sixteen, the two minds of calm abiding (śamatha) and special insight (vipaśyanā) are established separately.
