In Udaygiri of Madhya Pradesh the most important site is Varaha Cave. This is a early 5th century AD cave belonging to the Gupta period. More than cave this is a shallow niche.
Here one can see Lord Vishnu in Boar-headed incarnation, the Varaha. The relief depicts Varaha rescuing the Earth Goddess from the engulfing Ocean. Large Varaha which is 4 meter in height lifts Bhu Devi on his massive shoulder, while with his foot he subduing a naga who folds his hands in submission. There are also Gods and sages surround Varaha. Above his head there is also a circular lotus flower.
