成唯識論演祕 1.524

1.524

五識不親緣自外質，名為不稱。有云：初禪眼識見欲火災，相分與質不相似故，別種生故。

The five consciousnesses do not directly cognize their own external bases; this is called “not matching”. Some say: When the eye-consciousness of the first dhyāna sees the fire catastrophe of the desire realm, because the objective aspect and the external basis do not resemble each other, they arise from separate seeds.
