「第五、三性分別者，三性謂善、不善、無記。眼等六識通於三性，第七末那通於二性，謂善性、無記性，若在因位是無記性；若在果位及入觀時，當知是善性。第八阿賴耶識亦通二性，謂異熟無記及與善性；若在因位是異熟無記，若在果位即是其善。上來略料簡八識訖。」

"Fifth, regarding the distinction among the three natures: the three natures are the wholesome, the unwholesome, and the indeterminate. The six consciousnesses such as the cakṣur-vijñāna encompass all three natures. The seventh, the manas, encompasses two natures, namely, the wholesome nature and the indeterminate nature: at the causal stage it is of the indeterminate nature; at the resultant stage and when entering meditative contemplation, one should know that it is of the wholesome nature. The eighth, the ālaya-vijñāna, also encompasses two natures, namely, the ripened indeterminate and the wholesome nature: at the causal stage it is the ripened indeterminate; at the resultant stage it is wholesome. This concludes the brief examination of the eight consciousnesses above."
