Explanation:

Bankura is a city and a municipality in the state of West Bengal, India. It is the headquarters of the Bankura district.

In the Mahabharata, Bankura was described as Suhmobhumi. The word larh or rarh (in Nagari: ra?h) was introduced after 6th century A.D. It comes from the old Austric word rárhá or rárho which means “land of red soil”. 2-n ancient times "China called Rárh by the name of 'Láti'". 3-n Santali, lar means thread, rarh means tune and larh means snake. 4-.Perhaps the Jain and Greek scholars used this original Austric word larh to indicate this dry forest region which was very difficult. The popularity of Manasa Puja, the worship of Snake-Goddess Manasa, shows this opinion might have some relevance. According to Nilkantha, a commentator of the Mahabharata, the words suhmo [bhumi] (Sanskrit: suhma-bhumi) and Rarh are synonymous.
