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.
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.

Effortlessness means not doing anything, inactivity - AKARMA. Effort means doing much, activity - KARMA. Both have to be there. Do much, but don`t be a doer - then you achieve both. Move in the world, but don`t be a part of it. Live in the world, but don`t let the world live in you. Then the contradiction has been absorbed. Then you are not rejecting anything, not denying anything. Then the whole God has been accepted.
