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.
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.
