大方廣佛華嚴經疏 30.8

30.8

In the second part, practicing both the provisional and the real together, the opening clause establishes the tenet, taking non-obstruction as the tenet; the next clause provides the matching simile, just as illusory marks exist yet their essence is empty; finally, from 'knowing all' onward, it joins [the simile to the principle] and brings forth the rationale. 1. Because dharmas have no self-nature; 2. from 'contemplating all' onward, because contemplation is free from attachment—these two conform to empty suchness; 3. from 'knowing the real as it is' onward, because of knowing the single reality, it conforms to non-empty suchness; 4. from 'knowing all dharmas' onward concludes the accomplishment of non-contradiction; 5. from 'together with all' onward concludes what is done, meaning being able to enter the single path horizontally and enter the single gate vertically.
