In Jainism, Digambar and Shwetambar are the two main traditions (sects).

1. Meaning of the names

• Digambar (दिगम्बर)

- “Dig” = directions / sky, “ambar” = clothes - Meaning: “Sky‑clad” – wearing the sky as the only garment.

• Shwetambar (श्वेताम्बर)

- “Shweta” = white, “ambar” = clothes - Meaning: “White‑clad” – wearing white clothes.

2. Main visible difference

• Digambar

- Ideal monks do not wear clothes (complete renunciation of possessions). - They keep only very few things, like picchī (peacock‑feather broom) and kamandal (water pot).

• Shwetambar

- Monks and nuns wear simple white clothes. - They usually keep rajoharan/ogha (wool broom), bowl, muhpatti (mouth‑cloth), etc.

3. Scriptures and beliefs (in brief)

• Digambar

- Do not accept the present Shwetambar Āgams as fully authentic. - Have their own main texts (like Ṣaṭkhaṇḍāgama, Kaṣāyapāhuḍa, etc.). - Traditionally believe a woman must be reborn as a man to attain moksha in their line.

• Shwetambar

- Accept the Jain Āgam scriptures as authentic. - Believe that women can attain moksha in the female body.

4. What is common in both

Despite differences, both are equally Jain:

• Same goal: moksha (liberation from birth and death).
• Same core principles: ahimsa, satya, asteya, brahmacharya, aparigraha.
• Same faith in 24 Tirthankars, karma theory, and the three jewels:

- samyak darshan, samyak gyan, samyak charitra.
