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.
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.
The immediate source of a mind... must be a mind which existed before the conception took place; the mind must have a continuity from a previous mind. This we hold to prove the existence of a past life.
Still others commit all sorts of evil deeds, claiming karma doesn't exist. They erroneously maintain that since everything is empty, committing evil isn't wrong. Such persons fall into a hell of endless darkness with no hope of release. Those who are wise hold no such conception.
Dangerous consequences will follow when politicians and rulers forget moral principles. Whether we believe in God or karma, ethics is the foundation of every religion.
All major religious traditions carry basically the same message, that is love, compassion and forgiveness the important thing is they should be part of our daily lives.
