Thanks for bringing this thread to light. I had been hoping and thinking of talking about cymatics and wondering why no one seems to care much. As it is a great way to see the relationship between sound and matter. And it is a short leap between that and mind and matter.
People talk a lot about vibrations but don't really explore it deeply and just skirt the surface with metaphor. But for me all of material reality consists of standing waves. And with standing waves you can literally see through paradox. What is both standing still and moving at the same time? A standing wave does this just fine.
There is a cosmic song that is the prime mover of all creation. Eternal and ever-present. What is interesting is the source of the song and the dance as a living expression of the source.
