The Commentary explains: Practitioners of the three vehicles gradually cultivate and practice such yoga through hearing, thinking, and so forth, fulfilling it according to their lot, and in turn train and transform sentient beings; thus they are named yoga masters. Alternatively, the Tathāgatas, having completely realized yoga, maintain this yoga as appropriate and train and transform all noble disciples and so forth, causing them to gradually cultivate correct practice; thus they are named yoga masters.
