ekacittaḥ praśāntātmā śṛṇu mārtaṇḍanandana
yāmā nāma purā devā āsan svāyambhuvāntare //

"O Son of Mârtaṇḍa, hear attentively. In the bygone ages, at the close of the reign of Svâyambhuva Manu there was a group of Devas, known as Yâmas. In all Manvantaras, classes, such as Marîchi, &c., are recorded to have appeared. Svâyambhuva Manu had ten sons, viz.:—Agnîghra, Agnivâhu, Riphpha, Savala, Jyotiśmâna, Dyutimâna, Havya, Medhâ, Mêdhâtithi, Vasu. They having established a code of law and morality departed to felicity. This has been narrated as the Svâyambhuva Manvantara.—3-6.
