Explanation:

Kharavela was a king of Kalinga in present-day Odisha, India. The best known king of the Mahameghavahana dynasty, he ruled somewhere around first or second century BCE. His name is also transliterated as Kharabe?a.
The main source of information about Kharavela is his rock-cut Hathigumpha inscription. The inscription is undated, and only 4 of its 17 lines are completely legible. Different scholars have interpreted it differently, leading to a number of speculations about Kharavela's reign. The inscription credits the king with several welfare activities, patronage of arts, repair works and military victories. Although it exaggerates his achievements, historians agree that Kharavela was one of the strongest rulers of Kalinga.
Kharavela is believed to be a follower of Jainism, although the Hathigumpha inscription describes him as a worshipper of all religious orders.

The Hathigumpha Inscription consists of seventeen lines in a Central-Western form of Prakrit incised in a deep-cut Brahmi script on the overhanging brow of a natural cavern called Hathigumpha in the southern side of the Udayagiri hill, near Bhubaneswar in Odisha.
