The power of this mantra "om hrim shri arham namiun pasa visahar vasah jin fullinga hrim shrim arham namah swaha

This mantra is recited in Jain devotion as a stavan-like sacred mantra connected with Arham, Pārśvanāth, and protective devotional names.

Spiritual power in Jain understanding

Its power is understood as:

• Purification of mind
• Increase in devotion and concentration
• Calming of fear, anxiety, and negative thoughts
• Reminder of the qualities of Arihants and Tirthankars
• Support for inner strength, discipline, and detachment
• Helps the soul move toward right faith, right knowledge, and right conduct

Important Jain principle

In Jain Dharma, the true power of any mantra is not in words alone, but in:

• Shuddha bhavna — pure भावना
• Shraddha — right faith
• Samyak charitra — proper conduct
• Ahimsa, satya, aparigraha, and self-control

So this mantra should be chanted as a devotional aid for inner purification, not as a means of worldly miracle or harm.

Simple meaning

The mantra expresses salutation to the pure, victorious, compassionate, and protective qualities represented by the Arihants and Tirthankars.
