俱舍論頌疏論本 14.87

14.87

釋曰：前兩句者，離殺等四，名為戒支，防性罪故。離飲酒一，名不放逸支，酒必放逸，犯性戒故。離塗飾等三，名禁約支，以能隨順厭離心故。

The explanation says: As for the first two lines, abstaining from killing and the other four are called the branches of discipline, because they guard against intrinsic offenses. Abstaining from drinking alcohol, which is one, is called the branch of non-heedlessness, because alcohol inevitably leads to heedlessness and violation of intrinsic precepts. Abstaining from applying cosmetics and the other three are called the branches of restraint, because they conform to a mind of disgust and renunciation.
