The combined name of two of the द्वादशादित्यस् (twelve सूर्यस् ) मित्र and वरुण . These two are always seen together. अगस्त्य and वसिष्ठ were born as sons of मित्रावरुण . It was due to a curse by मित्रावरुणस् that उर्वशी had to marry King पुरूरवस् , a man of the earth. मनु had no children and he performed a याग to placate मित्रावरुणस् . But since there were many faults in the ceremony a girl was born to him. (For details see under Ilā, Nimi, Urvaśī, Vasiṣṭha and Mitra)
