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, emanated from these fourteen vowels. O-kāra (O-kara)is the fifth among the vowel-sounds emanated from the mouth of Brahmā. From O-kāra, Uttama Manu was born.

O-kāra was composed as a combination of five varṇa(s)(varna; the written form of dhvani or sound)
