(Kalpa in Sanskrit, Kappa in Pali). It is a fabulous period of four hundred and thirty two million years of mortals, measuring the duration of world. It is the period of time between other creation and recreation of a world or universe. The four kalpas of formation, existence, destruction and emptiness as a complete period, is called maha kalpa or great kalpas. Each great kalpa is subdivided into four asamkhyeya-kalpas or kalpas. Each of the four kalpas is subdivided into twenty antara-kalpas, or small kalpas. There are different distinctions and illustrations of kalpas. In general, a small kalpa is represented as 16,800,000 years, a kalpa as 336,000,000 years and a mahakalpa is 1,334,000,000 years.
