What are the four yugas?

The four ages

In the Puranic tradition, time moves in a great cycle made of four yugas. Each age has its own character.

Satya Yuga comes first. It is seen as a golden age, when dharma — right living — stands fully upright. People are long-lived, truthful, and close to the divine.

Treta Yuga follows. Things are still good but a little less so. Dharma is said to stand on three legs instead of four. Some moral decline has crept in.

Dvapara Yuga is the third age. Dharma stands on two legs. Knowledge and virtue have weakened further, and the world has grown more complicated.

Kali Yuga is the fourth and last age. This is the age the tradition says we are living in now. Dharma stands on one leg. It is seen as a time of confusion, conflict, and shorter lives. But it ends, and the cycle begins again with Satya Yuga.

What the cycle means

The four yugas are not just a timeline. They are a way of describing the state of the world at any given point. Each age marks how far the world has moved from balance and truth. The image of dharma losing legs is a way of picturing a slow decline, not a sudden fall.

The full cycle of all four yugas together is called a mahayuga. Many such cycles fit inside even larger spans of cosmic time. The scale is vast and deliberate — it places human history inside something much bigger, stretching far beyond any single lifetime or civilization.

Different traditions and texts describe the lengths and details of the yugas in varying ways, so there is no single agreed account of exactly how long each age lasts.

How people relate to it today

Most people who refer to the yugas today are not treating them as a literal scientific calendar. They use the framework to make sense of the world, to explain why things feel difficult, or to find comfort in the idea that no age lasts forever. The idea that Kali Yuga will eventually end and the cycle will start fresh gives the framework a hopeful quality even when it describes a dark time.

Scholars and scientists do not use the yuga system as a historical framework. It belongs to a cosmological view of time, not a measured one.
