In Jainism, Gyan (Jñān), Darshan, and Charitra are three very important spiritual pillars. Usually they are spoken of together as:

• Samyak Darshan – Right Faith / Right Vision
• Samyak Gyan – Right Knowledge
• Samyak Charitra – Right Conduct

Together they are called Ratnatraya (the Three Jewels) and they form the main path to moksha (liberation). ( jainknowledge.com)

Briefly:

1. Gyan (Jñān – Knowledge)

- Knowing the truth as described in Jain scriptures. - Understanding soul (jiva), non-soul (ajiva), karma, bondage, stopping of karma, shedding of karma, and moksha. ( jainknowledge.com)

1. Darshan (Faith / Vision)

- Having right belief in Tirthankars, soul, karma, and the path to liberation. - Free from wrong beliefs, doubts, and superstitions. ( jainknowledge.com)

1. Charitra (Conduct)

- Living daily life according to Jain vows: ahimsa, truth, non‑stealing, celibacy, and non‑attachment. - Controlling passions (anger, pride, deceit, greed) and following discipline. ( jainknowledge.com)

Relation between them

• Right Darshan gives correct attitude and trust in Jain path.
• Right Gyan gives correct understanding.
• Right Charitra is actually living according to that faith and knowledge.

All three must be present together for real spiritual progress.

Digambar & Shwetambar

• Both traditions fully accept these three as the basic path to liberation.
• Explanations and emphasis can differ slightly in texts and practices, but the core meaning is the same in both. ( jainknowledge.com)
