3.218

初三句舉妄，後三句顯真。可相者，相由心起，心於相上印可分別，故言可相，猶言相由心現。

The first three clauses raise the delusive; the latter three clauses reveal the true. "What can be marked": marks arise from the mind, and the mind ratifies and discerns upon marks; hence it is called "what can be marked," just as one says marks appear from the mind.
