Here is a simple, Jain-dharma focused meaning:

• Sutra (plural: sutras) literally means a thread. In general, it refers to a concise, compact statement or aphorism that ties together a teaching.
• In Jainism, sutras are the short, direct teachings that present core doctrines, ethics, and paths to liberation. They are meant to be memorized and contemplated, often forming the backbone of a larger teaching tradition.
• Sutras typically cover topics like right faith, right knowledge, right conduct, non-violence, truth, and the nature of karma and liberation.
• Different Jain traditions may have slight variations in the exact content or naming of sutras. For example, the Tattvartha Sutra is a well-known foundational text recognized across major Jain traditions, though its framing and enumeration can differ between Śvetāmbara and Digambara communities.

If you’d like, I can translate a specific Jain sutra into plain English and explain its core meaning, keeping to authentic Jain interpretation.
