चतुर्युग
The four great ages of time — and the wheel that forever turns from darkness back to light
Sanatana Dharma sees time not as a straight road running from a beginning to an end, but as a great wheel, turning through four ages again and again, without end. These four ages are the yugas. Together they form one vast cycle — a Mahayuga — after which the whole turning begins anew. The wheel never stops; darkness always returns to light.
In the beginning of the great cycle stands the Satya Yuga — the golden dawn of the world. In this age, dharma stands firm upon all four of its legs, perfect and whole. There is no falsehood and no fear. People live for hundreds of thousands of years, in harmony, pure of heart, with minds naturally turned toward the Divine.
Human beings do not need temples or rituals — they reach God simply by meditation. The lifespan is 100,000 years. There is no disease, no inequality, no need for effort in spiritual practice. It is the age of direct experience of truth.
In the Treta Yuga, dharma stands upon three of its four legs — truth, compassion, and austerity remain, but purity of the spontaneous kind begins to wane. People must now perform rituals and fire sacrifices (yajnas) to maintain contact with the Divine. Lifespans shorten to 10,000 years.
This is the age of Lord Rama — where dharma is still the guiding star, but must now be actively upheld against forces of evil. The battle of the Ramayana belongs to the Treta Yuga.
In the Dvapara Yuga, dharma stands upon only two legs, and the world grows harder still. Truth and untruth are now mixed in equal measure. Longing, illness, and discontent enter human life. Lifespans fall to 1,000 years. People must now use temple worship and devotion to God to find their way.
This is the age of Lord Krishna, the Mahabharata, and the Bhagavad Gita — where dharma must be fought for, where the field of Kurukshetra becomes a metaphor for the inner battle of every human soul.
And so we come to the Kali Yuga, the age in which we ourselves now live — when the bull of dharma stands upon a single leg. It is the shortest of the ages and the most clouded: lives are briefer (100 years), hearts more restless, and truth must struggle against falsehood on every side. Kali Yuga is said to have begun around 3102 BCE with the departure of Lord Krishna.
Yet the Puranas hold a tender secret about Kali Yuga — it is also the age in which liberation is easiest to attain. Simply chanting the name of God, even once with sincerity, is said to be enough. In the Kali Yuga, the Lord's mercy is at its most abundant.
All four yugas together = 4,320,000 years. The wheel then turns again from the beginning.
1,000 Mahayugas = one Kalpa = one day of Brahma = 4.32 billion years.
360 days of Brahma = one year. Brahma lives for 100 such years — a Mahakalpa.
We are in the 28th Kali Yuga of the current Kalpa — the Shvetavaraha Kalpa of the current day of Brahma.
