大般涅槃經集解 4.33

4.33

Sengzong says: Wisdom is compared to a field. Oxen are used to plow the field, and a field is considered fine when it is level and even. Here, using the goodness of body and speech to assist the mental karma is how one attains correct wisdom. Baoliang says: A field has the capacity to produce; if it is not plowed with oxen, its productive capacity will not be fulfilled. This is an analogy for how the karma of body and speech can fulfill the function of the mental sphere.
