abhiṣicya manuḥ putram ilaṃ jyeṣṭhaṃ sa dhārmikaḥ
jagāma tapase bhūyaḥ sa mahendravanālayam //

Vaivasvata Manu had ten powerful sons, the eldest of whom was Ila, who was born by the performance of putreṣṭi sacrifice. His brothers were:—Ikṣwâku, Kuśanâbha, Ariṣṭa, Dhriṣṭa, Nariṣyanta, Karuṣa, Śâryâti, Pṛiṣadhra and Nâbhâga, who were all very valiant and illustrious. Manu, after anointing his son Ila and putting the reins of the Government into his hands, went to practise asceticism in the forest called Mahendravana.—40-42.
