King Janak’s younger brother Kushadhvaja and his wife Chandrabhaga were parents of two daughters, Mandavi and Shrutakirti who married Lord Rama’s younger brothers, Bharata and Shatrughna. When their marriage was confirmed by the sages, their parents were on a pilgrimage and King Janak took the decision on their behalf. When they were informed about the good news, they were overjoyed to wed their daughters in the Raghuvanshi dynasty.
While Sita is an incarnation of Goddess Lakshmi, her sisters, Urmila, Mandavi and Shrutakirti are believed to be incarnations of Lord Vishnu’s weapons Adisesha, Sudarshan, and Panchajanya.
As per Uttara Kanda, Mandavi and Shrutakirti along with Lord Ram and his brothers immersed their mortal coil into River Sarju better known as River Sarayu (the largest tributary of River Sharada) in Uttarakhand. Originating from Sarmul, Sarju flows through many cities joining Mahakali at Pancheshwar.
