As a word of caution, this is not as simple as it sounds. It requires proper instruction from a Guru, the correct yogic positions and austerities, and a tremendous will power to take on this initiation.
This then is the circle of Divine sound in Hindu thought. We have journeyed from the mind of the enlightened rishi that was home to shruti – the first inspired thought. This thought precipitated as shabd, the first word and then into the multiplicity of the shlokas. Then came the speech or vaak, the rhythm and chhands that together gave birth to the sargam or music. All this combined in the Divine song or vaani.
We then reached the larger, more metaphysical concept of all sounds as Naad-Brahman and how it unfolds from Naad-bindu into all vocal and semiotic forms.
Next, we studied the matrika-chakra and learnt how the Divine and the akshara are intertwined. The Creation, the language, the human life processes are all part of One large symmetry. The Sanskrit alphabet reflects this symmetry in an amazingly profound manner leading to root verbs, its meters and other structures giving one the feeling of many more layers of meaning.
