Ūrjjā(Urjja) is the daughter of Prajāpati (Prajapati; Ruler of the people) Dakṣa (Daksha) , and wife of Vaśiṣṭha (Vasistha).
According to Bhāgavatapurāṇa (Bhagavatapurana), the children sired by Vaśiṣṭha (Vasistha), and born of the womb of Ūrjjā(Urjja) , are — Citraketu (Chitraketu), Virajā (Viraja), Suroci (Surochi), Mitra, Ulvaṇa (Ulvana), Vasubhṛdyāna (Vasubhridyana), Dyuman and others.

In Viṣṇupurāṇa (Vishnupurana) it is said that the seven sons of Vaśiṣṭha (Vasistha), born of the womb of Ūrjjā , are Rajaḥ (Rajah), Gātra (Gatra), Urdhavāhu (Urdhavahu) , Vasana, Anagha, Sutapā (Sutapa) and Śukra (Sukra).

According to Vāyupurāṇa (Vayupurana) , these sons of Vaśiṣṭha are: Raja, Putra, Ardhavāhu (Ardhavahu), Savana, Adhana, Sutapa, and Śukla (Sukla).
Ūrjjā and Vaśiṣṭha had a daughter called Puṇdarikā (Pundarika), too. In Brahmāṇḍapurāṇa (Brahmandapurana) , the daughter of Ūrjjā and Vaśiṣṭha is also mentioned.

In Mārkaṇḍeyapurāṇa, however, the names of the sons of Ūrjjā are given somewhat differently. They are — Raja, Gātra, Urdhavāhu, Savala, Anagha, Sutapā and Śūkta (Sukta).
