Karma is a uniquely Hindu concept. But its basic tenets are reflected in many religions. Thus, the Bible tells us, “As you sow, so you reap.” And further, “God will render to every man according to his deeds.” Judaism says, “He who is liberal will be enriched, he who waters will himself be watered.”
It is neither fatalistic nor punitive; nor is man a hapless, helpless victim in its bond. God has blessed each one of us with reason, intellect and discrimination, as well as the sovereign free will. Even when our past karma inclines us towards evil, we can consciously tune our inclination towards detachment and ego-free action, thus lightening the karmic load.
The doctrine of karma is essentially one of hope and encouragement.
