仁王般若經疏 3.152

3.152

第二供養法用，內有五句：初出般若置案上；二王行時以波若在前；三王行百步，般若放千里光；四令千里內無七難，得益也；五若住時作七寶座，以般若置上也。第二日日下，總明供養，法譬可解。

Second, concerning the method and function of making offerings, there are five clauses within it: first, bringing out the prajñā and placing it on the table; second, when the king travels, having prajñā precede him; third, when the king walks a hundred paces, prajñā emits light for a thousand li; fourth, causing there to be no seven calamities within a thousand li, which is the attainment of benefit; fifth, when staying, making a throne of seven jewels and placing prajñā upon it. Second, from 'day by day' onward, it explains offerings in general; the teaching and the metaphors are easily understood.
