梵網經菩薩戒本疏 6.147

6.147

上來別釋。「九戒」下，明結勸指廣，可知。「梵壇」者，此翻為默擯。良以非理違犯，不受調伏，故以此治之。彼之中明此義，故以為名，可知。

The above was the specific explanation. Below 'nine precepts', it explains the concluding exhortation pointing to wider texts, as may be understood. 'Brahmadanda' (fantan) is translated here as 'silent ostracism' (mobin). Indeed, because one has unreasonably violated [the precepts] and does not accept subjugation, one is disciplined by this means. Because this meaning is clarified therein, it is taken as its name, as may be understood.
