Here is a simple, respectful way to greet a Jain muni (monk):

• Stand at a respectful distance, facing the muni.
• Join your hands in prayer (palms together) and bow your head slightly.
• Say a brief greeting such as “Namaskar” or “Pranam.” Some people also say “Jai Jinendra” to show reverence.
• Keep quiet and avoid unnecessary movement or conversation while in the muni’s presence.
• Do not touch or come too close; avoid stepping in front of or pointing your feet toward the monk.

Notes:

• The core idea is reverence and non-violence. Whether you are in a Digambar or Shwetambar setting, the same gesture of folded-hands, a respectful bow, and a soft greeting is appropriate.
• If you are offering alms or meals, follow local temple guidance; many monasteries request no direct food offerings to a muni outside of formal, supervised contexts.
