The four Era, as we know them are Sat Yug (the Golden age), Treta Yug (the Silver age), Dwapar Yug (the Bronze age) and finally the Kali Yug (the Iron age – Present time) The four Yugas make up a cycle called Divya-yuga (Eternal Era), which lasts 4,320,000 years.
One thousand of these Yugas (Era’s) are equal to one day of Brahma*. This Period is known as Kalpa. Brahma’s lifespan is 100 years of his time. In each Yug there is a specific process of self-realization (Yug Dharma).
SAT YUG – (sometimes also called Krta-Yug): the Golden Age, lasted 1,728,000 years. The process of self-realization in this Yug was the meditation of Lord Visnu. During this Yug the majority of the people enjoyed a mode of goodness and the average life span at the beginning of the Yug was 100,000 years.
TRETA YUG – the Silver Age, lasted 1,296,000 years and the process of self realization was the performance of opulent Yagnas (sacrifices). The average life span was reduced to 10,000 years and the godly qualities decreased by one fourth compared to the Satya Yuga. It was during this age that Varna-Asrama-Dharma was introduced.
DWAPAR YUG – the Bronze Age, lasted 864,000 years and the process of self realization was the worship of the deities within temples offering charities. Idol worshiping was introduced plus certain vegetation was deemed to become obsolete. Such vegetation became known as Root-Vegetables such as carrots, potatoes etc. Godly qualities are reduced to 50% by now and the average life expectancy was only a 1000 years.
KALI YUG – the Iron Age, the age of hypocrisy and quarrel is to last 432,000 years. Lord Krishna appeared in His original, transcendental form right before the beginning of Kali Yug. The process of self realization is Kirtan, the chanting of the Holy Names of the Lord. God consciousness is reduced to mere 25% and life expectancy is only 100 years.
OBSERVATION: – By now already 5000 years of Kali Yug have passed with the prediction that by the end of this Yug people will hardly be older than 20 years and their only food intake will be meat.
* Brahma: More on his activities sometime in future. For now, I will try and explain in simple terms for those not familiar with his inventions:
Definition of GOD: Generator, Operator and Destroyer otherwise known as Brahma, Vishnu and Mahesh as believed and understood by Hindu community. Brahma being the Generator of the Galaxies. Certain scholors in the Puranas suggest an existance of Seven of these Galaxies.
