唯識二十論述記 2.278

2.278

Commentary: The upper two lines of the verse first explain through principle; the lower two lines of the verse adduce an analogy to establish it. It is because the one who kills serves as an adhipati-pratyaya, giving rise to a consciousness bent on killing, through its transformative power. It causes the one being killed to suffer harm, and the task of severing the life-faculty is accomplished. Therefore the killer incurs the sin of taking life, just as, through the mental intention of spirits and the like, other sentient beings lose mindfulness and so forth. This should be understood below.
