Answer

Yes, “Om Hrim Shrim Arham Namah” is commonly used as a Jain mantra, especially in devotional and meditative practice.

However, it is better understood as a short devotional mantra, not as one of the universally central Jain mantras like the Navkar Mantra.

Meaning

• Om – sacred sound used in spiritual practice.
• Hrim – a sacred seed syllable used for inner purity and spiritual energy.
• Shrim – a sacred seed syllable associated with auspiciousness.
• Arham – refers to the Arihant, the enlightened one who has destroyed inner enemies like anger, ego, deceit, and greed.
• Namah – respectful bowing or salutation.

So the mantra expresses:

“I bow with reverence to the Arham / Arihant.”

Takeaway

“Om Hrim Shrim Arham Namah” can be chanted as a complete short mantra for devotion and meditation. For daily Jain practice, the most fundamental and universally accepted mantra remains the Navkar Mantra.
