Kaal Chakra and Time units

Kalachakra (Wheel of Time) in Jainism

In Jainism, K alacakra (कालचक्र) means the Wheel of Time. Time is considered beginningless and endless, continuously rotating through cycles of rise and decline. Unlike a linear view of history, Jain cosmology sees the universe as passing through repeating time cycles.

This system of Kalachakra upcycle and downcycle exists only in 10/15 KarmaBhumi : 5 Bharat kshetras and 5 Airavat Kshetra

  1. Time itself (k ala) exists everywhere in the universe.
  2. Ara divisions are a special way of describing the changing social and spiritual conditions in certain human regions.
    • Only the 5 Bharat Kshetras and 5 Airavat Kshetras experience the dramatic cyclical "seasons of civilization" called the six Aras.
    • They describe changes in:
      • Human lifespan
      • Human height
      • Strength
      • Happiness
      • Morality
      • Availability of religion
      • Presence of Tirthankaras

Other regions do have time, but they do not necessarily have the six-Ara cycle.

The Two Halves of the Time Cycle

Each complete cycle consists of two periods:

1. Avasarpiṇi (Descending Cycle)

2. Utsarpiṇi (Ascending Cycle)

The cycle repeats forever:

Utsarpiṇi → Avasarpiṇi → Utsarpiṇi → Avasarpiṇi ...


Six Aras (Epochs) in Each Half-Cycle

Ara Name Nature Duration in Yugaliks Presence even in Karma Bhumi Presence of Tirthankar
1 Susam a-Susam a Complete happiness 4 Koda kodi sagaropam yes no
2 Susam a Very great happiness 3 Koda kodi sagaropam yes no
3 Susam a-Dusam a Happiness with slight sorrow 2 Koda kodi sagaropam yes yes
In last 84 Lakh Purva of this ara, 1st Tirthankar appears
4 Dusam a-Susam a Sorrow begins to dominate 1 Koda kodi sagaropam - 42k years no yes
Remaining 23 Tirthankars
5 Dusam a Predominantly sorrow 21k years no no
6 Dusam a-Dusam a Extreme sorrow 21k years no no

In Utsarpiṇi, these occur in reverse order.


Current Era

According to Jain tradition, we are presently in the:

5th Ara (Dusam a) of the current Avasarpiṇi.

Characteristics

The 24 Tirthankaras of our current cycle, ending with Mahavira, appeared during the 3rd and 4th Aras.


Duration of the Aras

The first four Aras are unimaginably long, measured in vast units such as S agaropama and Palyopama.

The last two are comparatively shorter:

Traditional Jain calculations place the start of the 5th Ara shortly after the nirv aṇa of Mahavira.


AVASARPINI (Decline) (In our area)

  1. Sushama-Sushama
    • 4 Koda kodi sagaropam

    • Remaining 23 Tirthankars
  5. Dushama ← Present Era

    • No Tirthankars
  6. Dushama-Dushama
    • 21k years
    • No Tirthankars

UTSARPINI (Rise)

  3. Dushama-Sushama
  4. Sushama-Dushama
  5. Sushama
  6. Sushama-Sushama

## Importance in Jain Cosmology

The K alacakra explains:
- Why Tirthankaras appear only during certain periods.
- Why human lifespan, height, and happiness vary across ages.
- Why spiritual opportunities differ across time.
- The cyclical nature of worldly existence (*saṃs ara*).

### Summary

> Time has no beginning and no end; it eternally revolves through Avasarpiṇi (decline) and Utsarpiṇi (rise), each consisting of six Aras.
