From his two arms, Pāñcajanya (Panchajanya) Agni (a form of the Fire-god) created two sounds, namely udātta (udatta) and anudātta (anudatta). Udātta is prākṛta svara (prakrita swara; the primary sound) to be employed during recitation of the Vedic hymns, whereas in the textual parts of Brāhmaṇa (Brahmana) it is considered vaikṛta svara (vaikrita swara; sound deformed from the original). Here five sages have been imagined as the fire or Agni. Prāṇa (Prana) is one of these five fire-like sages, whose sons name is Anudātta.
