in English, this person is a goofwad and makes my life HELL, so I must have burnt them alive in the 12th Century
I don't think that "assumption" is necessarily always true -- or ever true
because implicitly within that idea is the assumption of an "eye for an eye" causal relationship between past "actions" and current "re-actions"
when the truth is more likely that the situation in which you may find yourself is not grounded in "karmic debt" but instead really an opportunity for growth that is "hidden" within adversity
you don't "owe" something as much as you have "contracted" for a certain "type" of experience . . . by seeing adversity or conflict in this way, it is easier to "accept the lesson" and grow and, also, "move on"
we learn when we learn and not a moment before . . . everything in the "physical world" is an opportunity for growth and a chance to see ourselves through new eyeballs -- the true "purpose", I believe, of our earthly journey
