From oṁ (tataḥ) Brahmā created the group of sounds—the semivowels: ya, ra, la and va; the silibants: śa, ṣa and sa; the vowels: a, i, u e, o, ai, and au; the consonants from ka to ma; and short and long sounds of different intonations. Ādi indicates things like the visarga. He created the basic form (lakṣaṇam) of sounds.
