17.274

泰云：謂差善軛最勝臥具極處名邊際，惡人近靜室，謂可作婬處似定室。若能離邊際臥具及惡人靜室，即是善軛也，此捨名捨離善軛。

Tai states: 'It means that the best bedding and seats that are superior to the yoke of goodness are at the extreme end, hence called "marginal"; the quiet chamber frequented by evil people refers to a place where sexual misconduct can be committed that resembles a chamber of meditative concentration. If one can leave behind marginal bedding and seats and the quiet chambers of evil people, that is the yoke of goodness; abandoning this is called abandoning the yoke of goodness.'
