The cosmic cycle, also known as the Yuga cycle or the Mahayuga, is a recurring cycle of time in Hindu cosmology. It is believed to encompass the four Yugas, or cosmic ages: Satyuga, Treta Yuga, Dvapara Yuga, and Kali Yuga. Together, these ages form a complete cycle that repeats indefinitely.

The Yuga cycle is based on the idea that the universe undergoes periods of creation, maintenance, and dissolution. Each Yuga represents a specific phase in this cosmic cycle, with its own unique characteristics and qualities. As the cycle progresses, the moral and spiritual qualities of humanity are believed to decline gradually from the ideal state of Satyuga to the challenging state of Kali Yuga.

The complete Yuga cycle, or Mahayuga, is composed of 4,320,000 years. It is further divided into four Yugas, with each Yuga having a specific duration:

Satyuga (Golden Age): 1,728,000 years

Treta Yuga (Silver Age): 1,296,000 years

Dvapara Yuga (Bronze Age): 864,000 years

Kali Yuga (Iron Age): 432,000 years

After the completion of Kali Yuga, the cycle is believed to start again with the advent of a new Satyuga. This cyclical nature of time represents the rise and fall of human consciousness and the continuous evolution of the universe.

It's important to note that the Yuga cycle is a concept deeply rooted in Hindu mythology and religious beliefs. While it provides a framework for understanding the passage of time and the qualities of different ages, it should not be interpreted as a literal historical or scientific time measurement.
