Interpreted in Brahmasutra and Bhagavadgita
Theory of Karma
The ancient Vedantic knowledge reinforced by Brahmasutra and Bhagavadgita establish that it is, purely and solidly, the result (karmaphala) of earlier actions (karmas) of each one of the sentient entities. This is a strong and formidable solution to the unanswered questions like why does, one child being blessed to be born in either rich or healthy and sattvic family and another child being consigned to be born in a family living in poor conditions or unhealthy tamasic environment.
