Kalpa (time)

In Hindu and Buddhist cosmology, a "Kalpa" is a vast measure of time, often described as an epoch or a cosmic cycle. In Hindu texts, one Kalpa is equivalent to 1,000 cycles of the four Yugas, which are the ages of the world: Satya Yuga (the age of truth), Treta Yuga, Dvapara Yuga, and Kali Yuga (the age of darkness).
