Page "Karma" Paragraph 1

A concept of karma ( along with samsara and moksha ) may originate in the shramana tradition of which Buddhism and Jainism are continuations.

This tradition influenced the Brahmanic religion in the early Vedantic ( Upanishadic ) movement of the 1st millennium BC.

This worldview was adopted from this religious culture by Brahmin orthodoxy, and Brahmins wrote the earliest recorded scriptures containing these ideas in the early Upanishads.

Until recently, the scholarly consensus was that reincarnation is absent from the earliest strata of Brahminical literature.

However, a new translation of two stanzas of the Rig Veda indicate that the Brahmins may have had the idea, common among small-scale societies around the world, that an individual cycles back and forth between the earth and a heavenly realm of ancestors.

In this worldview, moral behavior has no influence on rebirth.

The idea that the moral quality of one's actions influences one's rebirth is absent from India until the period of the shramana religions, and the Brahmins appear to have adopted this idea from other religious groups.
