My guru determined by various calculations that the last kali yuga or Iron Age, of the Ascending Arc, started about A.D. 500. The Iron Age, 1200 years in duration, is a span of materialism; it ended about A.D. 1700. That year ushered in dwapara yuga, a 2400-year period of electrical and atomic-energy developments, the age of telegraph, radio, airplanes, and other space-annihilators.
