In the beginning of creation, fourteen svaradhvani(s) (swaradhvani; vowel-sound) were created from the four-mouthed Brahmā (Brahma). Manu, ruler of the fourteen Manvantara, was born of these fourteen vowels. Ū-kāra (U-kara) is the sixth among the voweḷ-sounds emanated from the mouth of Brahmā. From Ū-kāra, Cariṣnava(Charishnava) Manu was born. In Vāyupurāṇa (Vayupurana), these fourteen vowel-sounds are conceptualised as embodied gods. The embodied form of Ū-kāra is of yellow complexion.
