The Chakras

A Theosophical book of clairvoyant description, with colour plates, presenting the wheels as spinning discs and assigning them the rainbow spectrum — red at the base to violet at the crown.

Weld two, and the one that stuck to the retina. The rainbow is not in the Sanskrit. It is here, in 1927, from a Theosophist — and it is now on every chart in every studio and app in the world, presented as immemorial.
