I'd like to enquire as to the source of the quote on the page on Manvantaras:
"descends again into manifestation through the inner divine planetary thirst for active life …"
This is very accurate and authoritative but lacks a reference. I'm of the opinion that it derives from material predating the Hindu/Vedic tradition. Much of the fundamental cosmological doctrine preserved in the Vedas was inherited from far older times and traditions, and has since been overlaid by a mess of religious and pseudo-philosophical verbiage that obscures its meaning. This quote appears to have survived relatively intact, hence my interest.
With thanks for any replies, especially from the Wiki Owner
