A sculptured marvel at Mahabalipuram, often called "Arjuna's Penance", is an enormous relief made on two huge boulders. One of the biggest open-air rock canvases in the world, this bas-relief is 31m long and 9m high. The surface of the rock has detailed carvings, showing the most endearing and natural renditions of animals.

Critics are divided over the theme: one school believes that it shows Arjuna undertaking a penance to obtain a rare weapon against his enemies. The other believes that it depicts the legend of the River Ganges's descent to earth. According to them, cleft appeared in the rock dividing the canvas in two, when Shiva responded to Bhagirathas penance.

Arjuna's Penance, the exquisitely sculpted scene, which presents mans view of the universe, has over 100 figures of gods and semi divine creatures, birds and beasts, man and saint. All these figures are carved either facing or approaching the fissure and generally with hands folded in adoration.

The cleft in the rock depicts the descent of River Ganga (also known as Ganges), brought to earth by King Bhagiratha to redeem the cursed souls of his ancestors. On the left side of the fissure can be seen a simple temple which contains a four-armed deity, probably Shiva. The fissure is sculptured with Nagas. Above the fissure and on either side of it are flying figures of Gods and below are some sculptures of animals of which giant elephants are the most impressive and are considered to be the noblest creations of the human mind.

Arjuna, one of the Pandava brothers and a consummate archer, is shown standing on one leg, doing penance to obtain a boon from Lord Shiva. There is a forest with tribal people and all forms of animal life, just as they would appear in their habitat. Women are clothed in an aura of indescribable grace, a rich inner beauty transfiguring the plainest of them. The comic scene in the relief will amuse visitors where a cat is standing doing penance, while big and small rats are freely playing around the feline 'Tapaswi'.

A monkey family has also been depicted in a very exquisite and appealing manner. In the liveliness of each figure, one can notice the intense and naive love of life that characterizes the Buddhist art at Sanchi.
