6.163

六、輕重者，無知有多少，所化有利鈍，貪心有輕重，授戒有具闕，亦俱不俱等，輕重可知。

Sixth, on degrees of gravity: one's lack of knowledge has greater and lesser degrees; the ones being converted have sharp and dull faculties; the mind of greed has degrees of lightness and heaviness; conferring the precepts has completeness and deficiency; and these may be combined or not combined. The degrees of gravity can be understood [accordingly].
