Aarti geeth end of programme in Jain ceremonies usually means the concluding devotional songs (aartis) sung to express gratitude to the Tirthankaras and all revered beings, followed by a short bowing (vandana) and prayers. Here are the basics in simple terms:

• Aarti (lamp prayer): Aarti is a small ritual of offering light (diya or lamp) while singing devotional verses. In Jain gatherings, it signals the end of the programme and a moment to reflect on the path of right conduct and reverence for the Tirthankaras.
• Geet (devotional songs): These are melodious stutis or bhajans praising the Tirthankaras, the siddhas, and the Jain dharma. They help participants cultivate humility, gratitude, and inner peace as the event concludes.
• Namokar or Navkar Mantra: Many Jain end-of-program prayers include chanting the Namokar Mantra (with or without aarti) to bow to the enlightened beings and to seek right faith, right knowledge, and right conduct.
• Digambar vs. Shwetambar: There are regional/traditional differences in the exact texts and tunes used for aarti and stavan. If you want the precise end‑of‑programme text, tell me which tradition you follow (Digambar or Shwetambar) and I can provide the authentic wording and its arth (meaning).

If you’d like, tell me which tradition you follow and whether you want a simple English explanation or the original Jain text for a common end‑of‑programme aarti.
