"Sri Aurobindo’s study of Tamil, which he did with the help ;of Subramania Bharati, led him to discover that the “original connection between the Sanskrit and Tamil tongues” was “far closer and more extensive than is usually supposed” and that they were “two divergent families derived from one lost primitive tongue.” The artificial division between Indo-European and Dravidian languages had gone: “My first study of Tamil words had brought me to what seemed a clue to the very origins and structure of the ancient Sanskrit tongue.”"
