3.13

The words from 'The two vehicles' onward contrast the teachings in terms of depth. 'The third' is innate self-grasping. In the teachings of the two vehicles, it is stated that severing this is called the emptiness of the self. The words 'Hence humans and gods' and so forth mean that because those teachings only clarify the karmic conditions of good and evil and the favorable or unfavorable experiencing of retribution, they correspond to generating karma without knowing whence karma arises; therefore, the range of what their Dharma expresses does not reach the fourth.
