What is the spiritual meaning of salutation to the sun?
The sun is the outer symbol of the spiritual light within our subtle bodies. there are 3 dimensions of subtle body. the first is the subtle yet gross light of the emotions manifesting as chakras. The second is the light of the mind, insight we would say. The third is higher subtlest light comprised of wisdom, accessing the timeless quality of mind.
The pure sun is the light of the inner self - atma purusa. that light is who you are in essence. namaste mukunda
