This ushered in the Dvapara Yuga, or Silver Age. A spirit of competition arose among men and as a result the system of varnasrama, or class-based society, was introduced. However, as time progressed, people became less inclined toward spiritual practices and wished to augment their material comforts beyond their needs. It was a time of complete peace on Earth.

There was no war, famine, or conflict among the human race. Everyone enjoyed worldly comforts and lived in perfect harmony with the natural environment. The Vedic texts state that humans during Satya Yuga, or the Golden Age, lived for up to 100,000 years. In Satya Yuga, human beings were adept in meditation and possessed unbelievable strength and longevity. Just as there are four seasons to the calendar year, there are four yugas or universal seasons that make up an epoch of the cosmos. And of course you will also learn about our present age in Vedic time: Kali yuga. We also reveal amazing coincidences between Vedic history and the modern fields of cosmology and archeology. In this article we give an overview of each of the four yugas, Satya Yuga, Treta Yuga, Dvapara Yuga, and Kali Yuga, and we discuss concepts of Vedic time, including definitions of the most commonly used time units.

Like the four seasons of the year, the four ages of a chaturyuga, or Yuga cycle, rotate without end. Unlike the Western concept of linear time, Vedic time is cyclical. These four ages are known as Satya, Treta, Dvapara, and Kali. The four yugas refer to cosmic ages that are used in the Vedic / Hindu system for measuring universal time.
