華嚴經探玄記 18.26

18.26

Third, concerning the number of assembly leaders, there are two levels: 1. If speaking solely of persons, there are fifty-four persons, meaning that among the fifty-five assemblies, four assemblies have only one person, namely Mañjuśrī; furthermore, two assemblies each have two persons, namely Sarvagāmin and Śilpābhijña, together with the boy and girl. Therefore, while there are fifty-five assemblies, there are fifty-four leaders. 2. If identifying persons through the assemblies, there are fifty-seven persons, meaning that in two places among the fifty-five assemblies, one [person] is added to each, namely Sarvagāmin and so forth, as can be known.
