The history of the post- Mahavira period is never complete without mentioning the great division that took place among the Jainas during the centuries immediately following the passing away of Mahavira. Nobody knows exactly when this schism took place, but it is certain that famine conditions of the severest type extending to over several years in North India, where Jainas were preponderant and the inability of the Jainas-both householders and saints-to keep up to the standard of observance of the vows and conduct laid down in their tenets, were responsible for it.

The most important visible difference was in respect to clothing. The group which maintained that the saints even in their highest state of evolution need not discard clothing was named Shwetambara group (group with white clothing) and the group which maintained that in such highest state, it was necessary and incumbent upon the saints to discard all clothing, to the point of being and remaining for and at all times thereafter till death, completely naked, was named Digambara group (group with only
