Answer

In Jain Dharma, Navkar Mantra is considered the highest and most powerful protective mantra.

If you are asking for another prayer for protection from obstacles, fear, or harmful external influences, the most commonly recited one is:

• Uvasaggaharam Stotra — traditionally chanted for relief from difficulties and protection from troubles.

Explanation

• Navkar Mantra is supreme because it venerates the five supreme souls and brings inner protection through purity, humility, and spiritual strength.
• Uvasaggaharam Stotra is widely used by Jains when seeking protection from:

- difficulties - fear - physical or mental disturbance - unfavorable situations

It is especially associated with Lord Parshvanath and is traditionally regarded as a prayer that removes upasargas, meaning obstacles and afflictions.

Spiritual Understanding

In Jainism, true protection is not only from the outer environment, but also from:

• anger
• fear
• attachment
• ignorance
• karmic bondage

So the deepest protection comes from:

• Navkar Mantra
• Samayik
• Austerity
• Right conduct
• Equanimity

A prayer like Uvasaggaharam Stotra is helpful, but Jain teaching always places inner purification above outer remedy.

Takeaway

If you want a Jain prayer for protection other than Navkar Mantra, Uvasaggaharam Stotra is the most commonly accepted choice. But spiritually, Navkar Mantra remains the foremost protection mantra in Jainism.
