108 Parshwanath Ekasana Vidhi is a one-sitting chaityavandan (devotional chant) ritual venerating Lord Parshwanath with 108 nama (names/qualities). In Jain practice, ekasana (one sitting) versions exist in both Digambar and Shwetambar traditions, and the exact sequence/mantras can vary slightly between them. The general idea is: purify, establish reverence, chant or sing 108 names of Parshwanath, and perform the chaitya-vandan with appropriate mudras and devotion.

Key points you can rely on:

• 108 names (parshwanath bhagwan ke naam) are recited as a path toward right faith, clean conduct, and spiritual focus.
• The sequence and some mantras differ between Digambar and Shwetambar communities, but the spiritual aim remains the same: paying homage to Parshwanath and seeking auspicious virtues.
• Common elements seen in many versions include: starting with a consecration (mangal, invocations), khamsana mudra (a prayer gesture), and a sequence of verses or stotras praising Parshwanath.
