I'm a little flummoxed here; we are all owners of our kamma, heir to our kamma, etc. So how is it that unprofitable is not called one's own, while profitable is called one's own?Herein, the three kinds of bodily bad conduct, the four kinds of verbal bad conduct and the three kinds of mental bad conduct are not called one's kamma. The ten kinds of good conduct in the three doors is called one's own (saka) kamma. Whether it is of oneself (attana) or of another, all unprofitable is not called one's own (saka) kamma. Why not? Because it destroys benefit (attha) and promotes harm. Whether it is of oneself or of another, all profitable is called one's own. Why? Because it destroys harm and promotes good.
What am I missing?
Is it because in purifying oneself that which destroys benefit and promotes harm is left behind, while that which destroys harm and promotes good maintains the purification process? Something on this order?
