大般涅槃經義記 8.95

8.95

釋中，「所以」徵勸所由，下明其人欲師子吼，故應供養，於中有二：一明其人宿善今成，欲師子吼，故今供養；二「如師子王」下明吼同佛，故應供養。先喻，後合。

In the explanation, "Wherefore" inquires into the reason for the encouragement; below, it explains that because this person wishes to roar the lion's roar, one should make offerings, wherein there are two parts: first, it explains that this person's past goodness is now fulfilled and he wishes to roar the lion's roar, so one makes offerings now; second, from "Like the king of lions..." onward, it explains that his roar is identical to the Buddha's, so one should make offerings. First the metaphor, then the application.
