Namaskar. Here is a simple, Jain-docile explanation of the Jain time cycle (kalachakra) in easy terms, with a basic ASCII diagram. If you’d like, I can provide more exact divisions (numbers, names) from the Jain scriptures after checking authoritative sources.

What is the Jain time cycle?

• Time is seen as a vast wheel that repeats forever. It is not linear but cyclical.
• The wheel has two equal halves that keep turning: a rising period and a falling period.
• Each half lasts for a very long time, and within each half the world undergoes cycles of moral and physical flourishing and decline.

Two halves of the wheel

• Utsarpiṇī (the ascending period): In this half, human life and virtues ideally improve over many ages. People can progress in spirituality, and the world experiences increasing welfare.
• Avasarpinī (the descending period): In this half, moral decline gradually sets in, worldly difficulties increase, and spiritual progress becomes harder. The cycle eventually turns again toward a new Utsarpiṇī.

Simple, high-level diagram (ASCII)

• Imagine a circle that keeps turning. The line from the center to the edge represents “time moving forward.” The wheel turns from one half to the other, endlessly.

Start here (midpoint) | Avasarpinī end ---- Utsarpiṇī start | | [Descending] [Ascending] | | Avasarpinī end ---- Utsarpiṇī start | V

If you want a more detailed diagram, I can make a clearer ASCII art or a simple step-by-step flow:

• The wheel completes one full cycle consisting of two halves.
• Each half can be imagined as a long sequence of ages; during the ascending half, virtue tends to increase, and during the descending half, virtue tends to decrease.
• The cycle then repeats, so there is an ongoing pattern of rise and fall.

Key ideas you can take away

• Time in Jainism is cyclical, not linear.
• The two halves are alternating: ascending (utsarpiṇī) and descending (avasarpinī).
• The cycle continues without end, influencing the moral and spiritual conditions of beings and the world.
• There are many nuanced sub-details in the scriptures about the exact duration of each phase and the stages within them; these are described with precise terms in Digambara and Śvetāmbara commentaries and texts.

Would you like me to provide a more precise, scripture-based diagram and the exact names and numbers of the sub-ages within each half? I can fetch and present those details in a simple, clear diagram format.
