Answer

In Digambar Jain tradition, the main chant for protection is still the Navkar Mantra. Other than that, the most commonly used protective devotional recitation is the Bhaktamar Stotra, especially for peace, fearlessness, and removing obstacles.

Explanation

Strictly speaking, Jainism does not treat mantras like “magic spells.” Protection is understood through:

• remembrance of the Five Supreme Beings
• inner purity
• right faith, right knowledge, and right conduct
• devotional recitation with श्रद्धा, not superstition

In Digambar practice, people often recite:

• Bhaktamar Stotra — very popular for protection and overcoming difficulties
• Siddhachakra mantra / Siddhachakra worship — considered highly auspicious and spiritually protective
• Navkar Mantra — the highest and most universal Jain mantra

If you want one name besides Navkar, the safest answer is: Bhaktamar Stotra.

Spiritual Understanding

In Jain Dharma, real protection comes from:

• reducing karmic bondage
• staying शांत and संयमी
• remembering the Arihants and Siddhas
• living with non-violence and purity

So the mantra or stotra becomes a support for inner strength and spiritual safety.
