Here are simple Parshwanath Bhagwan mantras you can use:

• नमो पार्श्वनाथाय (Namo Parshwanathaya)
• नमो पार्श्वनाथाय नमः (Namo Parshwanathaya Namah)

Arth (meaning):

• नमो/Namo = salutations, bowing
• पार्श्वनाथाय = to Parshwanath Bhagwan, the 23rd Tirthankar

So, these mantras are expressions of reverence and request for the blessings of Parshwanath, the perfect yogi who embodies right knowledge and helps the soul move toward liberation.

Notes:

• These forms are commonly used and are consistent across Digambar and Shwetambar traditions, though some communities may use slight variant endings in daily practice.
• If you want, I can provide a longer Parshwanath stotra or a more elaborate dhyan (meditation) verse dedicated to him.
