Katyayana likens speech to the supreme Brahman. He uses the Rigvedic verse – Four are its horns, three its feet, two its heads, and seven its hands, roars loudly the threefold-bound bull, the great god enters mortals (Rig-Veda, iv. 58, 3), to assert this claim. Katyayana explains that in the verse, the four horns are the four kinds of words i.e. nouns, verbs, prepositions, and particles; its three feet mean the three tenses, past, present and future; the two heads imply the eternal and temporary words, distinguished as the manifested and the manifester; its seven hands are the seven case affixes; threefold bound is enclosed in the three organs the chest, the throat, and the head; the metaphor bull (vrishabha) is used to imply that it gives fruit when used with knowledge; loudly roars signifies uttering sound, speech or language; and in the great god enters mortals entails that the great god speech, enters the mortals.[9] Thus, primal sound is often referred to as Shabda Brahman or word as The Absolute.

• MNEMONIC TECHNIQUES
  • Vedic chantings use 4 tones –
    • udātta उदात्त (middle tone),
    • anudātta अनुदात्त (lower tone),
    • svarita स्वरित (higher tone)
    • dīrgha svarita दीर्घस्वरित (high tone extended). These are usually marked with intuitive svara marks – an underline for anudātta (अ॒), a small vertical line above the letter for svarita (अ॑) and two vertical lines for dīrgha svarita (आ᳚).
