This post made me really happy on some level... and brought me back to my own thinking of many years: "Whether Karma is real or not, we are best off leaving it alone."

Which means to me that we should just focus on living our lives and taking (our version of) "right action" as we walk our path. If there IS Karma, it will come in and set things right if someone wrong us, and if there is NO Karma, we will be able to sleep peacefully at night with the knowledge that we "did right" in the first place, regardless of what someone else might have done.
