The 4 elements and magical work

[Aion]

In your analogy, I think akasha would be like the song played by this octave of light.

I would actually view it the opposite, Akasha is the raw elements of sound and vibration and the 'music' is all the elements and displays that come from it. However, if you look at my structure, I have placed Akasha as being between the Third Eye and the Crown, correlating with the Form-maker body and thus actually the basis for all other forms.
