成唯識論演祕 4.211

4.211

此意以境有前及俱，故頌、長行對望說異，立名亦差。理實前境亦名色識，俱時之境亦名境色。

The intention is that because objects are both preceding and simultaneous, the verse and prose speak differently relative to each other, and the assigned names also differ. In actual principle, the preceding object is also called form-consciousness, and the simultaneous object is also called objective form.
