Taking this into account, the Maharishis divided time into four Yugas called Kritha Yuga, Dwapara Yuga, Thretha Yuga, and the Kali Yuga. These will keep coming back again and again. In these, the word Kritha indicates four times, and the word Thretha indicates three times. The Dwapara signifies two times, and Kali gives us an authoritative unit of measurement. According to them, 4,32,000 years is the basic unit and represents the number of years in a Kali Yuga. Two times this or 8,64,000 years represents the Dwapara Yuga. Three times this basic number of 12,96,000 years is the measure of Thretha Yuga. Four times this measure, namely, 17,28,000 years refers to Kritha Yuga. By adding all these, we get 43,20,000 years and this refers to a Maha Yuga. After a Maha Yuga, the Kritha Yuga will start again.
