Hope this is making sense..

It's all about sound. Light is sound.

There is plenty of info here, take it or leave it.

So, when you see colours you're actually seeing a musical note

The colour is vibrating at a certain frequency so you see that colour

If you knew how to harness the sounds from the suns light I believe you can heal anyone from anything. Just my opinion..
The sun is worshipped for a good reason..
Life wouldn't be here without it.

Pyramids are tuned to specific frequencies too.
Is it possible they used the suns light to harness its sound. Yes!

No man in the sky. Its all about the frequency.

I don't know too much about this for healing but let's say you replace the stones but keep the colours.. so the heart is green
Now use the frequency associated with green and play that over the heart to heal etc

The only way the stones make sense if those stones frequency matches the colours associated with certain parts of the body.
