大方廣佛華嚴經疏 30.8

30.8

二權實雙行中，初句立宗，以無礙為宗；次句同喻，如幻相有，體即虛故；後「知一切」下合，及出所因。一法無性故、二「觀一切」下觀無著故，上二順於空如；三「知如實」下知一實故，則順不空如；四「知諸法」下結成無違；五「與諸」下結成所作，謂能橫入一道、豎入一門。

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.
