Yuga (
Devanāgari: युग) in
Hindu philosophy refers to an 'epoch' or 'era' within a cycle of four ages: the
Satya Yuga (or
Krita Yuga), the
Treta Yuga, the
Dvapara Yuga and finally the
Kali Yuga, which are equated with Roman Golden, Silver, Bronze and Iron Ages respectively by E. Burgess . As per
Indian astronomy and Hindu Mythology the world is created, destroyed and recreated every 4,320,000 years (
Maha Yuga) . The cycles are said to repeat like the seasons, waxing and waning within a greater time-cycle of the creation and destruction of the universe. Like Summer, Spring, Winter and Fall each yuga involves stages or gradual changes that the earth and the consciousness of mankind goes through as a whole. A complete yuga cycle from a high Golden Age of enlightment to a Dark Age and back again is said to be caused by the solar system's motion around a central sun.
