The Niyamasara — the Essence of the Rule — is a jewel of Jain spiritual literature, composed by the revered Digambara teacher Kundakunda in the early centuries of the Common Era. Written in the living Prakrit of its day, this concise masterpiece unfolds the soul's journey from confusion to liberation. Kundakunda teaches that karma binds us not through outward circumstance but through the soul's own wrong belief, passion, and activity — and that freedom dawns when right faith, right knowledge, and right conduct become one in the soul's abiding awareness of its own pure nature. This modern-English edition renders Kundakunda's verses in clear, inviting prose while remaining faithful to the original's meaning and contemplative spirit. An engaging introduction, notes, a glossary, and passages for reflection make the text accessible to readers new to Jain thought as well as to those who already cherish it.
