首楞嚴義疏注經 2.388

2.388

此依俗諦具緣能見為難。唯識說九緣，此唯出四，約小乘義，減大五緣，心即分別緣也。

This raises an objection relying on the conventional truth that seeing is capable of occurring when equipped with conditions. Vijñānavāda speaks of nine conditions, but here only four are brought forth; in terms of the Hīnayāna meaning, five conditions of the Mahāyāna are subtracted, and "mind" is the discriminative condition.
