"Of Sanskrit, Sri Aurobindo writes: Every one of its vowels and consonants has a particular inalienable force which exists by the nature of things and not by development or human choice; these are the fundamental sounds which lie at the base of the Tantric bija-mantras and constitute the efficacy of the mantra itself. Every vowel and every consonant in the original language had certain primary meanings which arose out of [some] essential Shakti or force, and [these] were the basis of other derivative meanings."
