Understood. In Jain Dharma, the common terms for a geographic area are desh or pradesh (both meaning a country/regional zone). The word region, if used in English, can imply a non‑physical or vague area, so it’s better to translate with one of these precise terms when referring to Jain texts.

• Use desh or pradesh for earthly/geographic areas.
• If you’re talking about non‑earthly realms (like the various lokas or heavens/hells in cosmology), name the specific loka (e.g., uttar lok, madhya lok, adho lok) rather than a vague “region.”
• If you mean a conceptual or spiritual sphere, you can indicate it as a “desha” in a metaphorical sense, but clarity is best achieved by specifying the exact context (earthly region vs. cosmological realm).

If you share a line or source you’re translating, I can suggest the most precise Jain term to substitute for “region.”
