A yuga is a cosmic age according to the Vedic system of measuring universal time. The four yugas — Satya Yuga, Treta Yuga, Dvapara Yuga, and Kali Yuga — comprise one full yuga cycle, and one thousand Yuga cycles is equal to a day of Brahma, also known as a kalpa.

In this article we discuss Satya Yuga, the Golden Age.

The Duration of Satya Yuga

In Vedic cosmology, various regions within the universe experience time differently due to the phenomenon of time dilation. For example, one year in the realm of Svarga is approximately equal to 720 solar years on our planet Earth.

For this reason, the Vedas give two different measurements for the duration of Satya Yuga. In years of the devas, Satya Yuga lasts 4,800 years, and on Earth, it lasts 3.456 million years. The duration of Satya Yuga is described in the Vayu Purana as follows:

Four thousand years constitute the Kṛta [Satya] Yuga, which is also called the Prakriyāpāda. Four hundred years constitute the Saṃdhyā and four hundred years the Saṃdhyāṃśa, which are transition periods at the beginning and end of the Yuga, respectively. (Vāyu Purāṇa 1.32.55-56).

The most recent Satya Yuga ended approximately 4.33 million years ago.

Time Unit Solar Years
 Kali Yuga 0.864 million years
Treta Yuga 1.728 million years
Dwapara Yuga 2.592 million years
Satya Yuga 3.456 million years

General Overview

In Satya Yuga, human beings were adept in meditation and possessed unbelievable strength and longevity. The Vedic texts state that humans during Satya Yuga, or the Golden Age, lived for up to 100,000 years. There was no disparity among cultures. Everyone enjoyed worldly comforts and lived in perfect harmony with the natural environment. There was no war, famine, or conflict among the human race. It was a time of complete peace on Earth. However, as time progressed, people became less inclined toward spiritual practices and wished to augment their material comforts beyond their needs. A spirit of competition arose among men and as a result the system of varnasrama, or class-based society, was introduced. This ushered in the Dvapara Yuga, or Silver Age.
