In other words, on what ‘basis’ the result for your actions are determined. I have seen very many references to how we should live our life so we accumulate Good Karma etc. in Vedic and non- Vedic sources like Sathyam Vadha, Dharmam Chara etc. I have also seen that we should not depend on the result of our actions and in fact offer that itself to Brahman in Gita.
However, I have not seen any direct reference on the basis of Karma phala determination in any source very clearly. There are some hints. I also know divisions of Karma (Sanchitha, Prarabda etc.) and what accumulates, what doesn’t, and what we bring into when we are born and what we carry forth when we leave etc. as well as Nitya Karma. But not very clear on how Karma phalam is determined.
Any scriptural references as to how this is determined would help. Without proper and clear definition, and grey areas, there are loopholes that entities could make use of for justifying immoral, unethical and overall incorrect actions correct?
Any proper scriptural references appreciated. Older the better.
My question is different from Origin of Karma and such references from scriptures.
For e.g Who decides for e.g "being high up in heaven, an eternity with Surya, eternal life, a long life, being invited first, becoming chief of your village, a horse, a bullock, gold, food, a bride, the light of heaven, the Universe" AS RESULTS for your good karma of "giving Dakshina to the Brahmanas performing your Yagna". What is the Justification for such a result assignment and not something else?
More generally, What MUST be the Scriptural BASIS of such RESULT assignment for Good OR Bad Karma? Whoever may be the decider.
How am I to find out if this is in Rig Veda that is not Tampered by Vyasa's Sishya for e.g? Where are the cross references? If you leave the result vague and ad-hoc instead of a Sound scriptural basis then the adoption of Good Karma is Vague too correct? That is the motivation behind this question.
