1. Where to keep them

- Best places: - Near/above the main entrance of the house. - In or just outside the pooja room / home temple. - Avoid: - Floor where people walk, put footwear, or where they can be stepped on. - Near dustbin, bathroom, or any unclean place. ( jainknowledge.com)

1. How to treat them

- Keep the area clean and respectful. - Remember they are symbols to remind you of right faith, knowledge and conduct, not objects for worldly wishes only. ( jainknowledge.com) - If they are printed or framed, handle them like any other sacred Jain image (don’t throw them casually if old or damaged; dispose respectfully).
