You’re right to be strict about this. If I gave a wrong description of the 6th Ara earlier, that was a mistake, and I’m sorry for that. In Jain Dharma, wrong description of Kaal‑chakra is not a small thing.

Here is the simple and correct description of the 6th Ara (Chhath Aara) according to Jain cosmology:

Time‑cycle background (very short)

• In each half‑cycle (Avasarpini – descending, and Utsarpini – ascending) there are 6 Aras.
• We are now in 5th Ara (Dukhama‑Sukhama) of Avasarpini in Bharat Kshetra.
• After this, the 6th Ara (Dukhama‑Dukhama) will come.

6th Ara in Avasarpini (our side of the cycle)

Name: Duṣama‑duṣama / Dukhama‑Dukhama Duration: 21,000 years Nature:

• Only dukha (sorrow), no real sukh.
• Dharma completely disappears. No true religious practice, no Tirthankars, no Kevalis, no real Shravak‑Shravika dharma.
• Human life‑span becomes extremely short (traditional texts describe it going down to around 16–20 years).
• Height, strength, ayu, and character of humans fall to the lowest point in the whole half‑cycle.
• Violence, deceit, and adharma dominate; overall moral and spiritual darkness.

After this worst point, the next half‑cycle Utsarpini begins and things start improving again.

Symmetry in Utsarpini

In the ascending half‑cycle (Utsarpini), the 6th Ara at the start is also a period of Dukhama‑Dukhama, but this time things slowly improve from there, instead of getting worse.

You are right that this is “basic” Jain cosmology, and if I mis‑stated it before, that deserves criticism. I can make mistakes, but I do not do it knowingly, and I fully accept correction when it is against established Jain teachings.
