After that great Being, O mighty-armed one, viz., Consciousness, had sprung, an exceedingly beautiful lotus, possessed of effulgence like the Sun's, grew out of the navel of the Supreme Being (floating on the waters). Then, O son, the illustrious and divine Brahman, the Grandsire of all creatures, sprang into existence from that lotus, irradiating all the points of the horizon with his effulgence. After the high-souled Grandsire had, O mighty-armed one, thus sprung from the primeval lotus, a great Asura of the name of Madhu, having no beginning, started into birth, springing from the attribute or Darkness (Tamas). The foremost of all Beings, (viz., the Supreme Divinity), for benefiting Brahman, slew that fierce Asura of fierce deeds, engaged even then in the fierce act (of slaying the Grand-sire). From this slaughter, O son, (of the Asura named Madhu), all the gods and the Danavas and men came to call that foremost of all righteous persons by the name of Madhusudana (slayer of Madhu). After this, Brahman created, by a flat of his will, seven sons with Daksha completing the tale. They were Marichi, Atri, Angiras, Pulastya, Pulaha, Kratu, (and the already mentioned Daksha). The eldest born, viz., Marichi, begat, by a fiat of his will, a son named Kasyapa, full of energy and the foremost of all persons conversant with Brahma. From his toe, Brahman had, even before the birth of Marichi, created a son. That son, O chief of Bharata's race, was Daksha, the progenitor of creatures.
