[To my mind like ( A ) is symbolically and akin to √-1 , similarly the other 3 primary vowels also have possible other mathematical symbolic representations. As a suggestion this could work on the lines that ( [ ) is the exponential ‘e’; ( ] ) is like π and ( ? ) is like the number system ?? There is a mathematical coding….but this needs to be investigated further.]

The mutes also begin with ( kM ) as Prajāpatī and ( KM ) as shūnya or zero. Both are also equated to Brahman representing the increasing side and decreasing side of creation.

4. The Semi – Vowels are the antahstah or they reflect the inner energies. Their significance in the Chakra system is that they comprise the bīja for the first four Chakras viz.      ( ya ) the 4^th or the Heart – Anāhat Chakra ; ( r ) the 3^rd or the Navel – Manipūr Chakra ; ( va ) the 2^nd or the genitals – Swādhisthān Chakra ; ( la ) the 1^st or the lower Pelvic – Mūldhār Chakra. It would be interesting to look at these and some conjugal words e.g. yam ( yama ) – māyā ( maayaa ) ; vis ( ivaYa ) – śiva ( iSava ) ; there is a metaphysical representation which is need further perspicacity.
5. The Sibilants, also called the Fricatives are the Ūsma ( Sa ), ( Ya ), ( sa ) and ( h ) . These can be linked to the three Shaktīs ( SaR ), ( ]Yaa ), ( satI )…the energies of the manifest universe. Their consorts are Brahmā , Viśnu and Shiv…the two different ś and s….conjugate words. In the Vedic system energy is treated very differently from the western scientific method.

shri is the countable domain. Here the energy transactions are conserved. That is what leaves one spot diminishes from there and increase at the receiving end.
