Answer

A commonly chanted Jain mantra for Rishabh Dev is:

ॐ ह्रीं श्री आदिनाथाय नमः Om Hreem Shri Adinathaya Namah

Since Rishabh Dev is also known as Adinath, this mantra is widely used in devotion.

Explanation

This mantra is a respectful salutation to Bhagwan Rishabh Dev, the first Tirthankar of the present time cycle in Jain tradition.

You may also use the more universal Jain mantra:

णमो अरिहंताणं Namo Arihantanam

This honors all Arihants, including Rishabh Dev.

Spiritual Understanding

Chanting a mantra with devotion helps the mind become शांत, pure, and focused.

In Jain Dharma, remembrance of a Tirthankar is not for asking worldly favors, but for:

• purifying thoughts
• reducing attachment and anger
• increasing श्रद्धा and inner discipline
• moving toward आत्मशुद्धि

Takeaway

If you want a simple and respectful Rishabh Dev mantra, use:

ॐ ह्रीं श्री आदिनाथाय नमः
