金剛般若經贊述 2.213

2.213

無著云，法身雖無形相，而有法性之相，謂理媚曰相也。於外化中亦有形相，為令眾生得此種圓滿故，謂內證真理無相之相故，而外具有相之相也。然有相之相即非無相之相，是名諸相具足也。

Asaṅga says: Although the dharmakāya has no physical marks, it has the marks of the Dharma-nature; that is, the grace of principle is called 'mark'. In external manifestation there are also physical marks. This is to cause sentient beings to attain this kind of fulfillment: that is, because internally they realize the mark of the markless true principle, externally they possess the marks of having marks. However, the marks of having marks are not the marks of marklessness; this is called the completeness of all marks.
