成唯識論演祕 3.27

3.27

因種在滅，果種在生，應同種現，名果俱有。設爾何失？若爾，種子生現，現生種，二竟何別？俱果俱故。故疏結云何為料簡？又違《瑜伽》。

If the causal seed is in ceasing and the fruitional seed is in arising, then like seed and active, they ought to be termed 'coexisting with the fruit'. Even if so, what fault is there? If so, what difference would there ultimately be between a seed producing an active [dharma] and an active [dharma] producing a seed? Because both would coexist with their fruits. Thus the Commentary concludes by asking, what is the point of discrimination? Furthermore, it contradicts the Yogācārabhūmi.
