「由二所依至慚愧心故」者，答。一依相續，非起二貪可發善戒，由二根所依身所起煩惱於一相續身俱增上故不發善戒。於正思擇有堪能者可發善戒，扇搋迦於正思擇聞、思、修等無堪能故不發善戒。極慚愧心能發善戒，半擇迦無有極重慚愧心故不發善戒。又解：半擇迦於正思擇無堪能故，扇搋迦無有極重慚愧心故。又解：俱通二種。又解：總通三種。

Regarding 'Because of possessing the basis of both [organs] ... to ... because of [lacking] a mind of shame and modesty': this is the reply. Within one continuum, the emergence of two kinds of lust cannot generate the wholesome vows (saṃvara); because the afflictions arisen in a body that possesses the basis of both faculties are both intensified in a single mental continuum, wholesome vows are not generated. Wholesome vows can be generated in someone capable of correct discernment (pratisaṃkhyāna); a ṣaṇḍha does not generate wholesome vows because they lack the capacity for correct discernment through hearing, reflection, cultivation, and so on. An intense mind of shame and modesty can generate wholesome vows; a paṇḍaka does not generate wholesome vows because they lack an exceedingly strong mind of shame and modesty. Another explanation: because a paṇḍaka lacks capacity for correct discernment, and a ṣaṇḍha lacks an exceedingly strong mind of shame and modesty. Another explanation: both reasons apply to both types. Another explanation: they apply across all three types.
