6.199

六、輕重者，眾生有難易，悲心有厚薄，方便有多少，不勸有暫永，亦有俱等，准前。

Sixth, lightness and gravity: sentient beings have difficulty and ease [of being transformed], the compassionate mind has depth and shallowness, skillful means have many and few, not exhorting has temporary and permanent; there are also combinations of them, to be assessed as before.
