Quotes:Samvartta Kalpa
H. P. Blavatsky
Samvartta Kalpa. The Kalpa or period of destruction, the same as Pralaya. Every root‐race and sub‐ race is subject to such Kalpas of destruction; the fifth root‐ race having sixty‐four such Cataclysms periodically; namely: fifty‐six by fire, seven by water, and one small Kalpa by winds or cyclones.
