> While speaking, you see, I went back to the origin of sound > (Sri Aurobindo describes it very clearly in Savitri: the origin of > sound, the moment when what we called 'the Word' becomes > a sound). Which book, canto is this described in Savitri ? > This put me in contact with that whole world and I began > speaking to him a little about what I had already said to > you concerning my experience with the Vedas.

We have another description of what the Mother might have experienced. See the last chapter of Hymns to the Mystic Fire called Word Formation which describes the creation of Devabhasha I shall first indicate the principle on which the roots of the devabhāṣā were formed. All Shabda (vāk) as it manifests out of the ākāśa by the force of mātariśvan, the great active and creative energy, and is put in its place in the flux of formed things (apas) carries with it certain definite significances (artha). These are determined by the elements through which it has passed. Śabda appears in the ākāśa, travels through vāyu, the second element in which sparśa is the vibration; by the vibrations of sparśa, it creates in tejas, the third element, certain forms, and so arrives into being with these three characteristics, first, certain contactual vibrations, secondly, a particular kind of tejas or force, thirdly, a particular form. These determine the bhāva or general sensation it creates in the mind and from that sensation develop its various precise meanings according to the form which it is used to create.
