梵網經菩薩戒本疏 6.90

6.90

六、輕重者，於前四緣各有多少，俱不俱等準前應知。又此五中前二稍輕，後三應重，三中如次下、中、上差別可知。

Sixth, relative gravity: regarding the former four conditions, the distinctions of more or less, occurring together or not, should be understood as before. Furthermore, among these five, the first two are slightly lighter, and the latter three should be heavier; among the three, the distinctions of lower, middling, and upper can be understood in order.
