King Priyavrata sired a son named Idhnajihva (Idhnajihwa), born of the womb of Varhiṣmatī (Varhishmati), daughter of Prajāpati (Prajapati; Ruler of the people) Viśvakarmā (Viswakarma). Priyavrata appointed Idhnajihva, to be the ruler of Plakṣadvīpa (Plakshadwipa, the island of Plaksha).
Idhnajihva divided Plakṣadvīpa in seven varṣas (varsha; a vast plot of land) and distributed them among his seven sons. The names of Idhnajihva’s seven sons are : Śiva (Siva), Suramya, Subhadra, Śāntya (Santya), Śapta (Sapta), Amṛta (Amrita) and Abhyaya. According to Skandapurāṇa (Skandapurana), Idhnajihva got to rule over Gomeda dvīpa (dvipa, island) and he divided this island among his seven sons. That is why the seven varṣas of Gomeda dvīpa are named after the seven sons of Idhnajihva.
