I want to know the answer to the following question:
Scholars believe that karma originated in what?
All the background I'm provided with is that "Scholars have reasons to believe that ideas such as samsara, karma (in the sense of the influence of morality on rebirth), and moksha originated in the shramanas, and were later adopted by Brahmin orthodoxy.[note 18][note 19][note 20][note 21][note 22][note 23]". Is that enough to answer the question?
Answer: yes
