What is "shanta"

Shanta is a character in the Ramayana. She was the daughter of Dasharatha and Kausalya, elder sister of Rama, Bharata, Lakshmana and Shatrughna and played crucial role in their birth, adopted by the couple Rompad and Vershini. Shanta was married to Rishyasringa, son of the legendary Indian Hindu saint Vibhandaka. The descendants of Shanta and Rishyasringa are Sengar Rajputs who are called the only Rishivanshi rajputs.

She is not mentioned in the original Valmiki Ramayana but originates in the followed up regional tellings of the great epic.
