There is a vital plane (self-existent) above the material universe which we see; there is a mental plane (self-existent) above the vital and material.

They have been established in the earth-consciousness by evolution – but they exist in themselves before the evolution, above the earth-consciousness and the material plane to which the earth belongs.
