Etymology goes back further to the dawn of thought, much further than archaeology or paleography.
The root of the oldest words is all that remains of time that no memory can imagine. These roots are the minute, ineffaceable traces of what was once pure intuition, radiant knowledge, sudden revelation, for singular men and moving crowds.
The ancient roots, still alive, like verbal souls, speak to us of a vanished world.
Among the most powerful roots are those that inform the names of the Gods.
In the Veda, Agni is said to be « Fire ».
But the truly original, etymological meaning of the word « agni » is not « fire », it is « alive », and « agile ».
The idea of « fire » is only a derivation from this primeval sense. The oldest intuitions associated with the word « agni » then are « life » and « movement », as opposed to « rest » and « death ».
The divine Agni, had indeed many other names, to tell of his other qualities: Atithi, Anala, Dahana, Vasu, Bharata, Mātariśvā, Vaiśvānara, Śoṣaṇa, Havyavah, Hutabhuk…
Agni’s names all have a distinct, specific meaning. Atithi is « Host », Anala is « Longevity », Dahana is « Burning », Tanūnapāt : « Self-Generated », Apāṃnapāt : « from the waters ».
So many attributes for such a hidden God!
« Two mothers of a different color and walking quickly, each giving birth to an infant. From the breast of one is born Hari [yet another name of Agni], honored by libations; from the breast of the other is born Soucra (the Sun), with a bright flame ». i
Agni is indeed « visible », He was born as a child, – but very clever, very wise is whoever can really « see » Him !
« Which of you has seen Him, when He is hiding? As an infant just now, there He is who, by the virtue of sacrifice, now gives birth to His own mothers. Thus Agni, great and wise, honored by our libations, generates the rain of the cloud, and is reborn in the bosom of deeds.» ii
Agni is everywhere. Agni is not only « alive », « agile », He is not only « Fire », not only « God ».
He is also the flickering glow, the sparkling lightning, the blazing forest, the fatal lightning, the evening sun, the pink dawn, the inflexible flint, the warmth of the body, the embers of love…
To understand the Veda, it helps to be a poet, to expand one´s mind to the universe, and even farther away.
