疏「故唯四門不出事理」下，第三收五為二。言四門者，謂上雖五意，但有四門：一事、二理、三事理雙泯、四事理無礙。故前三意但是事理，三四二門不出事理，故為二也。

Regarding the commentary's "Therefore only four gates do not depart from phenomena and principle" onward: the third, gathering the five into two. Speaking of the four gates: although there are five intents above, there are only four gates: 1. phenomena, 2. principle, 3. phenomena and principle both extinguished, 4. non-obstruction of phenomena and principle. Therefore, the preceding three intents are simply phenomena and principle, and the third and fourth gates do not depart from phenomena and principle, so they make two.
