I have come to some conclusions as to how in the primitive stages the language could have evolved, though over the time it could have got mixed up and complex.
The diagram expresses how the various alphabets in Indian languages give the direction and the approximate distance, when a person lets out a vowel. Depending on the intensity with which one speaks, either the seriousness of the issue is revealed, or the distance gets multiplied. Thus a अ அ gives Y axis, e इ இ gives X axis, and u उ உ gives Z axis etc,and aa आ ஆ , ee ई ஈ and uu ऊ ஊ give the farther end of the same. ae ए எ gives the angular direction in the Y positive X negative quadrants and also X positive Y negative quadrants, and o ओ ஒ gives the same in XY both positive or both negative quadrants. औ ஔ gives the torque or turning momentum, and ஃ emphasizes static point. Thus i ஐ ई becomes origin or subtle vertical movements about the origin and thus becomes 'I' the self. When a person stands before you he forms z axis with you, and thus Uu becomes 'you'. In Hindi it is 'thum', and in Tamil, eventhough Nee is in X axis,it travels in z axis direction and comes back, Un, ungal etc form Z axis with I. He, She, Him, Her etc in any language form an arc in the speaker's eyeball and get away from the sight, settles in the low regions above the horizontal plane, X axis-Zaxis.
This logically leads to the other conclusion- Ka -Ga mean Solids, and Sa -Cha mean liquids; gas being not visible got submerged in Ya and Va. Some studies are to be made on Da and Ta which are basically Noice indicative. Na and nNa indicate sensitiveness (electricity). Pa is indicative of one's Pushing ability when challenged, and 'Ma' the cries let out by one when faced with distress. 'Ra' may mean slicing through in a rough way, and 'La' may express excitement.'zha' in Tamil is lubricating and meaning the softness of the commodity. Thus is formed a rash analysis of how the languages could have evolved.
