Short, clear answer:

• A soul that is born in the 4th āra (chautha kāl) but does not attain moksh in that same 4th āra

Reason in simple terms:

1. Moksh is possible only where and when:

- Tirthankars / Kevalī Bhagwāns are present, - And the spiritual era (ārā) is suitable.

1. According to Jain scriptures (both Digambar and Shvetāmbara traditions agree):

- In the present 5th āra (Pancham Kaal) of Bhārat and Airāvat Kṣetra, - No Tirthankar is born, - No Kevalī arises, - No soul attains moksh from here. ( jainknowledge.com)

1. So if someone was born in 4th āra, then:

- If they reached kevaljnān and moksh while the 4th āra was still going on → moksh is possible. - If they missed that chance and time has moved to 5th āra, then they can only create strong causes (karmic punya + samvar–nirjarā) in 5th āra, and later attain moksh in some future suitable era/region (for example, Mahāvideh Kṣetra or a future good āra).

So:

• No direct moksh from Bhārat in 5th āra,
• Yes, the same soul can attain moksh later, but in a different place/time, after finishing the necessary karmas.
