How does the Three Jewels teaching guide Jain spiritual life?

In Jainism, the Three Jewels—right knowledge, right faith, and right practice—serve as the essential foundation for spiritual life and the path to moksha. These three elements must be cultivated simultaneously, as none can be fully realized in isolation.21

• Right Faith: This fosters tranquility, detachment, and kindness, while encouraging the renunciation of pride related to status, beauty, wealth, or fame.2
• Right Knowledge: This involves a clear distinction between the self and the nonself. Knowledge is considered futile without the accompanying faith and conduct.2
• Right Practice: This is the spontaneous application of moral conduct, which is deeply rooted in the doctrine of nonviolence (ahimsa).2

Spiritual discipline, or yoga, integrates these jewels to purify the mind and guide behavior. While the specific requirements for conduct differ between the laity and ascetics, the overarching moral code remains grounded in the avoidance of injury through thought, speech, and action. Ultimately, this ethical framework is designed to lead the practitioner toward the liberation of the soul.21
