Theory of Karma - As Interpreted in Brahmasutra and Bhagavadgita

Creation is a process, where the potential insentient matter (prakr̥ti) gets manifested into the gross form, to embody during the sr̥ṣṭi, each of the sentient entities called the ātmas with the suitable body either of deva, manuṣya, jaṅgama or of sthāvara. This glorious activity is orchestrated by the one and only Omnipresent, Omnipotent and Omniscient Reality called Brahman. But one question remains still an enigma, as to why a particular sentient entity gets a specified body and through whose direction that decision arrives? The ancient Vedāntic knowledge reinforced by the Brahmasūtra and the Bhagavadgītā establishes that it is, purely and solidly, the result (karma-phala) 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 sāttvic family and another child being consigned to be born in a family living in poor conditions or unhealthy tāmasic environment.
