In Jain usage, Shalin (शालिन) generally means someone who is calm, composed, and self-controlled—a virtuous and well-behaved person. It conveys inner restraint and gentleness, qualities revered in Jain conduct (ahimsa, tapas, and mental discipline).

Notes:

• It is a descriptive quality, not a technical doctrinal term.
• There isn’t a different meaning for Digambara vs. Śvetāmbara traditions; both view a calm, disciplined demeanor as desirable.

If you were thinking of a specific scripture or name that includes “Shalin,” tell me the exact context and I can clarify further.
