A kalpa is a long period of time (aeon) in Hindu and Buddhist cosmology, generally between the creation and recreation of a world or universe.[1]
Kalpa (Sanskrit: कल्प||a formation or creation) in this context, means "a long period of time (aeon) related to the lifetime of the universe (creation)." It is derived from कॢप् (kḷp) + -अ (-a, nominalizing suffix) (Sanskrit: कॢप्|kḷp|to create, prepare, form, produce, compose, invent).[2] [3]
See also: Hindu units of time, Manvantara and Yuga Cycle. In Hinduism, a kalpa is equal to 4.32 billion years, a "day of Brahma" (12-hour day proper) or one thousand mahayugas, measuring the duration of the world. Each kalpa is divided into 14 manvantara periods, each lasting 71 Yuga Cycles (306,720,000 years). Preceding the first and following each manvantara period is a juncture (sandhya) equal to the length of a Satya Yuga (1,728,000 years).[4] A kalpa is followed by a pralaya (dissolution) of equal length, which together constitute a day and night of Brahma. A month of Brahma contains thirty such days and nights, or 259.2 billion years. According to the Mahabharata, 12 months of Brahma (=360 days) constitute his year, and 100 such years his life called a maha-kalpa (311.04 trillion years or 36,000 kalpa + 36,000 pralaya). Fifty years of Brahma are supposed to have elapsed, and we are now in the Shveta-Varaha Kalpa or the first day of his fifty-first year. At the end of a kalpa, the world is annihilated by fire.[5]
The definition of a kalpa equaling 4.32 billion years is found in the Puranas—specifically Vishnu Purana and Bhagavata Purana.[6]
The Matsya Purana (290.3–12) lists the names of 30 kalpas, each named by Brahma based on a significant event in the kalpa and the most glorious person in the beginning of the kalpa. These 30 kalpas or days (along with 30 pralayas or nights) form a 30-day month of Brahma.[7]
The Vayu Purana has a different list of names for 33 kalpas, which G. V. Tagare describes as fanciful derivations.[8]
In the Pali language of early Buddhism, the word kalpa takes the form kappa, and is mentioned in the assumed oldest scripture of Buddhism, the Sutta Nipata. This speaks of "Kappâtita: one who has gone beyond time, an Arahant".[9] [10] This part of the Buddhist manuscripts dates back to the middle part of the last millennium BCE.
Gautama Buddha claimed an incalculable number of Buddhas lived in previous kalpas: Vipassi Buddha 91 kalpas ago, Sikhi Buddha 31 kalpas ago, and three prior Buddhas in the present kalpa.[11] He confines his teachings to the present kalpa, the duration of which he doesn't arithmetically define, but uses a similitude:
A similar similitude is found in the Mountain Pabbata Sutta (SN 15:5) of the Pali Canon:[12]
Described in the Vibhanga division of the Abhidhamma Pitaka are sixteen rupa brahma lokas (worlds or planes) and four higher arupa brahma lokas, each attained through the imperfect, medial or perfect performance of the four states of jhāna (meditation), granting a duration of life measured in kalpas that exceed the top-most heavenly loka of 9.216 billion years:
At the termination of each kalpa, the lower three rupa brahma lokas, attained through the 1st jhāna, and everything below them (six heavens, Earth, etc.) are destroyed by fire (seven suns), only to later again come into being.
In one explanation, there are four different lengths of kalpas. A regular kalpa is approximately 16 million years long (16,798,000 years[13]), and a small kalpa is 1000 regular kalpas, or about 16.8 billion years. Further, a medium kalpa is roughly 336 billion years, the equivalent of 20 small kalpas. A great kalpa is four medium kalpas,[14] or about 1.3 trillion years.
Gautama Buddha did not give the exact length of the maha-kalpa in terms of years. However, he gave several astounding analogies to understand it.
In one instance, when some monks wanted to know how many kalpas had elapsed so far, Buddha gave the below analogy:
Another definition of Kalpa is the world where Buddhas are born. There are generally 2 types of kalpa, Suñña-Kalpa and Asuñña-kalpa. The Suñña-Kalpa is the world where no Buddha is born. Asuñña-Kalpa is the world where at least one Buddha is born. There are 5 types of Asuñña-Kalpa:[17]
The previous kalpa was the Vyuhakalpa (Glorious aeon), the present kalpa is called the Bhadrakalpa (Auspicious aeon), and the next kalpa will be the Nakshatrakalpa (Constellation aeon).[18]
