Bodhidharma on Lineage

Student: The layperson has a wife and children, so he can not yet cut out sexual desires. How can he become Buddha?
Bodhidharma: …If you saw the self nature, sexual desire would already be void and serene; there would be nothing to cut out; there would be nothing to attach to; even though one may still have habitual potentiality, it would not be disruptive.
Student: Killing is a butcher’s jop; how can they attain Buddhahood?
Master: I have told you just to see the self-nature; not about the resulting karma; although one who saw self-nature is creating karma, still, he is different from the confused ones; that is, all variety of karma would not imprison him.
