梵網經菩薩戒本疏 3.30

3.30

第三、次第者，前四同聲聞四重，此戒非彼，故在第五。又五戒中此當第五不飲酒戒，但以飲唯損己一身，過未深故屬下輕垢，酤損多人故今制重。又為菩薩二利之中利他為最，但乖益生已為非理，況乃成損故非所宜，是故未論自飲先制授他。

Third, regarding the sequence: The preceding four correspond to the four major [precepts] of the śrāvakas; this precept is not among those, hence it is in fifth place. Furthermore, among the five precepts, this corresponds to the fifth precept of abstaining from alcohol; however, because drinking harms only one's own single body, the fault is not yet grave, so it belongs below among the minor defilements; selling harms many people, so here it is instituted as a major [offense]. Moreover, for a bodhisattva, among the two benefits, benefiting others is supreme; merely violating the benefiting of beings is already improper, how much more so when it actually causes harm, which is utterly unbefitting; therefore, before discussing drinking oneself, handing it to others is first prohibited.
