大般涅槃經義記 5.363

5.363

上來別竟，「如是」下結。「如是等善，慈為根本」結末依本。「以是義」下結慈是實。「若人問」下重顯向前慈為行本，初先假問，後對顯之，「以是義」下重結慈實。

The specific explanation above is finished; from 'such' downward is the conclusion. 'Such wholesome [dharmas] have loving-kindness as their root' concludes that the branches rely on the root. From 'for this reason' downward concludes that loving-kindness is real. From 'if someone asks' downward reiterates the preceding point that loving-kindness is the root of practice: first raising a hypothetical question, and afterwards setting forth the explanation in response; from 'for this reason' downward reiterates that loving-kindness is real.
