The Mahabharata of Krishna-Dwaipayana Vyasa

Sauti said, 'One chariot, one elephant, five foot-soldiers, and three horses form one Patti; three pattis make one Sena-mukha; three sena-mukhas are called a Gulma; three gulmas, a Gana; three ganas, a Vahini; three vahinis together are called a Pritana; three pritanas form a Chamu; three chamus, one Anikini; and an anikini taken ten times forms, as it is styled by those who know, an Akshauhini.

The study of the Bharata is an act of piety. He that readeth even one foot, with belief, hath his sins entirely purged away.
