“Shams” isn’t a standard Jain term, but you might be referring to one of these:

• Śama (shama): inner tranquillity or calming of passions. In Jain Dharma it means pacifying anger, pride, deceit, and greed, so the soul steadies itself on the path of right conduct.
• Kṣamā (kshamā): forgiveness. Central to Jain ethics and Paryushan; it is seeking and granting forgiveness to reduce karmic bondage.
• Śramaṇa (shraman): an ascetic/monk or nun who follows the Jain path of restraint and non‑violence.

If you meant one of these, the above is the Jain meaning; say which one you had in mind and I can expand with scriptural details and traditional explanations.
