The Tamsa rises in a tank at Tamakund in the Kaimur Range at an elevation of 610 metres (2,000 ft) in the Maihar district.

In the evening, Rama, Lakshmana, and Sita and all the people reached the banks of the Tamsa.

Rama and everyone agreed to spend the night at the banks of the Tamsa river and continue the journey the next morning.

[5] The ashrama of sage Valmiki is regarded to have been located at the banks of the Tamsa river.

Sita is believed to have spent most of her remaining life here, and her twin sons Lava and Kusha received education and trained in military skills under Valmiki's tutelage.
