2.101

意不定應知者，應知意界四事不定，謂意有時與身、識、法四皆同地。有時上下，於遊等至及受生時，隨其而應，或同或異。如後定品當廣分別。已上七段總是傍論竟，次辨正論。

'Mind should be understood as indeterminate': it should be known that the mind element is indeterminate with respect to four matters. That is, the mind sometimes is of the same level with all four—body, consciousness, and phenomena; and sometimes it is higher or lower. When wandering in meditative attainments and when taking rebirth, according to what is appropriate, they are either the same or different. This will be broadly distinguished in the later Chapter on Meditative Attainments. The above seven passages conclude the parenthetical discussion; next, the main treatise will be distinguished.
