Besides Navkar Mantra, a Jain shravak can recite several other prayers and mantras. Here are common ones, with their basic intent:

• Ucchhavan Mantra

- Purpose: auspicious beginnings and purification. - Text essentials: Om Hreem Shreem (used at start of activities).

• Arihantaya Namah

- Purpose: obeisance to Arihants (enlightened beings who have conquered inner enemies).

• Siddhaya Namah

- Purpose: obeisance to Siddhas (liberated souls).

• Acharyaya Namah

- Purpose: obeisance to the Revered Teacher (Acharya).

• Upadhyaya Namah

- Purpose: obeisance to the Upadhyaya (spiritual preceptor in a monastic community).

• Chaitya Vandana (in temple worship)

- Includes several components sung or recited during a formal Chaitya Vandana: - Namaskar Mahamantra - Logassa Sutra - Khamasaman - Chattari Mangalam - Tassa Uttari - These form a traditional sequence for temple prostration and homage.

• Mangalacharan

- Purpose: auspicious beginning prayer before any ritual or study.

Notes on tradition:

• These prayers are used across Digambar and Śvetāmbar traditions, though exact texts and sequences can vary slightly between sects.
• Bhaktāmara Stotra is a widely recited Jain hymn (stotra) praising the Jina; it is treated as a devotional prayer and is popular in both sects, but its verse count and some verses differ between Digambaras and Śvetāmbaras.
