Answer

For Ashtottari Puja in Jain tradition, the commonly recited mantra is based on offering worship with 108 names or praises of the Tirthankar or Arihant Bhagwan.

A simple and widely appropriate mantra during the offering is:

ॐ ह्रीं श्री अरिहंत परमात्मने नमः।

Or, if worshipping a specific Tirthankar, for example Bhagwan Mahavir:

ॐ ह्रीं श्री महावीर स्वामिने नमः।

Explanation

“Ashtottari” means 108. In Ashtottari Puja, devotees usually offer flowers, rice, or other pure dravya while reciting 108 names or devotional praises.

The mantra may vary depending on:

• Which Tirthankar is being worshipped
• Shvetambar or Digambar tradition
• Local sangh or temple practice
• The specific Ashtottar Shat Namavali being used

Spiritual Understanding

The purpose of Ashtottari Puja is not merely recitation, but to develop:

• Devotion toward Arihant Bhagwan
• Purity of thought, speech, and action
• Humility and surrender of ego
• Inspiration to follow the path of samyak darshan, samyak jnan, and samyak charitra

Takeaway

You may recite:

ॐ ह्रीं श्री अरिहंत परमात्मने नमः।

with devotion, but for the exact 108-name Ashtottari Puja text, it is best to follow the version used by your temple, guru, or Jain tradition.
