四分律行事鈔資持記 3.724

3.724

四中，初制後至。故在後者，謂自恃已尊，意欲動眾；今時多然，聞須深誡；但能蘊德，自使他尊；豈唯計校，以謂光榮；雖可罔於無知，實取笑於有識。亦下，次開不起。縱是尊長，非所宜故。若下，三明留位。此謂知彼有緣而未至者。

In the fourth [heading], it first prohibits arriving late. Arriving late intentionally means presuming on one's own high status with the intention of causing a stir in the assembly. Nowadays this is common; upon hearing this, one must be strictly warned. If one can merely harbor virtue within, it will naturally cause others to show respect; how could it be that petty calculation alone constitutes glory? Though one may deceive the ignorant, one actually incurs the ridicule of the discerning. From 'Also...' onward, the second permits not rising: even if it is a senior elder, it is inappropriate. From 'If...' onward, the third explains saving a seat: this refers to cases where one knows another has a valid reason and has not yet arrived.
