When a person influences another individual in a positive way, that measure of positive influence is credited for all eternity. Moreover, when the second individual utilizes that same positive influence to then affect others, the positive energy generated is also accrued to the original person. This same principle holds true with all of our negative actions.
Our inability to perceive the far-reaching implications of our actions, allows us to behave wantonly and with disregard for others. These verses give us the understanding and enlightenment to foresee all the repercussions associated with our behavior, motivating us to constantly improve our ways through continued spiritual development.
