二、釋去已更不去，二：初、正解釋。「非是善去」者，由前三教果理俱未究竟，故非善去也。「去已猶應更去」者，謂去至取相更去偏真，乃至去但中更去圓中。

Second, explaining 'having gone, not going again', in two: first, direct explanation. 'Not being well-gone': because in the previous three teachings neither the fruit nor the principle is ultimate, they are not 'well-gone'. 'Having gone, one should still go further' means going as far as grasping characteristics, then going further to biased truth, and even going to mere center and then going further to the perfect center.
