The present form of the doctrine seems to be unchanged at least since the time of Bhadrabahu (c. 300 BCE) who is respected by both the sects. This is supported by the fact that both Svetambara and Digambara sects agree on the basic doctrine, giving indication that it reached in its present form before the schism took place. Bhadrabahu is usually seen as the last leader of united Jain sangh. Detailed codification of types of karma and their effects were attested by Umasvati who is regarded by both Digambara and Svetambara as one of theirs.
