Nala’s grandson who married the daughter of the Aryavarta king Chitravarma – Seemantini. The princess had heard of Chandrangada when she was young and had had fallen in love with him. She married him with the help of Yajnavalkya’s wife Maitreyi. Once Chandrangada went to the Kalindi river for a boat race with his friends. The boats were all sunk in a sudden storm. Many died, but Chandrangada was dragged down by Thakshaka’s henchmen. He lived there for a while in the company of the naga princesses. His subjects, meanwhile, thought him dead and conducted his last rites. Seemantini lived as a widow and enemies defeated the old king Indrasena, imprisoned him and took over Chandrangada’s kingdom. Meanwhile, Thakshaka asked Chandrangada to marry the naga princesses and live there. He then told Thakshaka that he would like to return to Seemantini.

Thakshaka sent him on a white horse and gifted him a rakshasa and a young naga. He surfaced at Kalindi, where Seemantini had started staying. When the news spread, the other kings released Indrasena and apologised to Chandrangada. He forgave them. Both husband and wife had much faith in somavaravrata. Parvati was pleased by Seemantini’s devotion and blessed her.

Two brahmins named Saraswata and Devamitra were living in the kingdom then. Their sons were  Samava, and Sumedha respectively, who were all learned, but poor. Because of this, they couldn’t find wives. They approached Chandrangada and Seematini in the hope of getting some money. They narrated the story, and then Seemantini got Sumedha and Samava to don the garbs of groom and bride respectively and parade around the palace. After the parade was over, Samava remained a female and Seemantini named her Samavati. Saraswata learned of this and asked sages if this could be reversed, but couldn’t. They opined that only Parvati could. From then on they lived as husband and wife as per Shivapurana Somavaravrata.
