Digambara Jainism
 

This is the earlier and more austere of   Jainism , which is a, ancient, Nastik philosophy propounded by saints called Tirthankaras. Dig means direction or space, and ambar means clothes, such that Digambar means `clothed in space' or naked. The nudeness of Digambar Jains symbolises complete emancipation from physical and social constraints. Mahavira, the last of the Jain Tirthankaras who lived in the 6th century B.C., went about nude without  being affected by sun, wind or rain. His band of followers too were nude, and this may have been the genesis of the Digambara Jains. During the time of Chandragupta Maurya, Ganadhari Bhadrabahu , a renowned scholar, led the Digambara Jains south so as to survive a famine. Returning after several years, he then went away to Nepal , to breathe his last there.
