Jain cosmology: According to Jain beliefs, the
universe was never
created, nor will it ever cease to exist. Nor is it controlled by an all powerful
deity. Time is divided into
Utsarpinis (Progressive Time Cycle) and
Avsarpinis (Regressive Time Cycle). An Utsarpini and an Avsarpini constitute one Time Cycle (Kalchakra). Every Utsarpini and Avsarpini is divided into six unequal periods known as Aras. During the Utsarpini half cycle,
ethics,
progress,
happiness,
strength,
age,
body,
religion, etc. , go from the worst conditions to the best. During the Avsarpini half-cycle, these notions deteriorate from the best to the worst. Jains believe we are currently in the fifth Ara of the Avsarpini phase, with approximately 19,000 years until the next Ara. After this Avsarpini phase, the Utsarpini phase will begin, continuing the infinite repetition of the Kalchakra.
The oldest Jain literature is in Ardha-Magadhi and Maharashtri Prakrit (Agamas, Agama-tulya, Siddhanta texts etc).
According to Jain beliefs, Jain philosophy is a codification of eternal universal truths which at times lapse among humanity, but later reappear through the teachings of human beings who have gained enlightenment or omniscience (Keval Gnan).
