In Svāyambhuva (Swaymbhuva) Manvantara, Ūrṇā (Urna) was the wife of Prajāpati (Prajapati; Ruler of the People) Marīci (Marichi). Six righteous sons, sired by Marīci, were born of the womb of Ūrṇā. They were known as ‘Ṣaḍgarbha’ (Sadgarbha). Cursed by Brahmā (Brahma), these six sons of Ūrṇa were reincarnated in their furture births as the sons of Kālanemi (Kalanemi) and afterwards, as sons of Hiraṇyakaśipu (Hiranyakasipu).
