Cosmic year (Chinese astrology)
Vedic scriptures delineate a cosmic cycle of creation and destruction marked by 4 Yugas. There is considerable debate on the duration of one Yuga, varying from 1200 to 432,000 or millions years. Swami Sri Yukteswar Giri estimates the duration of two total cycles (an descending and an ascending part) to comprise 24000 years. According to Vamadeva David Frawley the Yuga cycle relates to the precession of the equinoxes, thus suggesting a relationship with the platonic year. In the interpretations of these and other vedic scholars, modern times (1700–1900) have witnessed the end of the dark "Iron Age" (Kali Yuga), a notion supported by Rudolf Steiner.
