Yes. In Jain Dharma, you can offer a prayer for someone’s well-being and for the smooth success of a medical procedure.

Jain prayer is usually not a request to a creator, but a sincere expression of bhav:

• goodwill for the person,
• peace of mind,
• strength,
• and support for wholesome causes and good karma.

A simple Jain prayer you may say is:

“Arihanta, Siddha, Acharya, Upadhyaya, Sarva Sadhu Bhagwantone namaskar. Aa vyakti ne sukh, shanti, bal ane swasthya male. Aapda bhava shuddha rahe ane sarva mangal thao.”

Meaning:

• I bow to the Arihants, Siddhas, Acharyas, Upadhyayas, and all Sadhus.
• May this person receive peace, strength, and good health.
• May my intention remain pure, and may auspiciousness prevail.

A very common and powerful Jain recitation is the Namokar Mantra:

Namo Arihantanam Namo Siddhanam Namo Ayariyanam Namo Uvajjhayanam Namo Loe Savva Sahunam

You may recite it with the feeling:

“May this person be protected, may the procedure go well, and may there be peace and wellbeing.”

If you want, I can also give you:

• a short prayer in Gujarati,
• a formal Jain stotra-style prayer, or
• a very simple one-line prayer for daily use.
