大般涅槃經義記 3.139

3.139

下佛先呵，「何以下」釋，先問、後解。解中有二：一對向後句明戒具在、二「於乘緩」下對向前句明戒不緩。前中，初明自行清淨故戒具在，「如堤塘」下令他戒淨故戒具在，「若有清淨持戒」已下結明戒在。自行淨中，「本所受戒如本不失」明專護持，「設有」已下明犯已悔。

Below, the Buddha first rebukes him; from 'Why is this?' onward explains, first questioning and then resolving. Within the resolution there are two parts: first, addressing the latter clause, clarifying that the precepts remain complete; second, from 'lax regarding the vehicle' onward, addressing the former clause, clarifying that they are not lax regarding the precepts. In the former part, it first clarifies that because one's own practice is pure, the precepts remain complete; from 'like an embankment' onward, [clarifies that] because they cause the precepts of others to be pure, the precepts remain complete; from 'if there is a pure precept-holder' onward concludes and clarifies that the precepts remain. In 'one's own practice being pure,' 'the precepts originally received are not lost from their original state' clarifies single-minded protection and upholding; from 'even if there is...' onward clarifies repenting after committing [a fault].
