I have this tattooed on my left side! I love the saying and it's a perfect description of Karma, don't judge/discriminate and don't do to someone what you wouldn't want done to you.
The virtues we acquire, which develop slowly within us, are the invisible links that bind each one of our existences to the others - existences which the spirit alone remembers, for Matter has no memory for spiritual things.
Unless you see your nature, you shouldn't go around criticizing the goodness of others. There's no advantage in deceiving yourself. Good and bad are distinct. Cause and effect are clear. But fools don't believe and fall straight into a hell of endless darkness without even knowing it. What keeps them from believing is the heaviness of their karma. They're like blind people who don't believe there's such a thing as light. Even if you explain it to them, they still don't believe, because they're blind. How can they possibly distinguish light?
...the counsels of the Divine Mind had some glimpse of truth when they said that men are born in order to suffer the penalty for sins committed in a former life.
The present moment, though, is outside of time, it’s Eternity. In India they use the word “karma” for lack of any better term. But it’s a concept that’s rarely given a proper explanation. It isn’t what you did in the past that will affect the present. It’s what you do in the present that will redeem the past and thereby change the future.
