Answer

I think you may mean the “Labh Shanti Mantra” or a Jain Shanti Mantra, but the phrase “laugh shanti mantra” is unclear.

Sorry, I can only provide information that is clearly established within Jain tradition.

Clarification

If you are asking for a Jain mantra, please confirm which one you mean, for example:

• Labh Shanti Mantra
• Jain Shanti Path
• Namokar Mantra
• Uvasaggaharam Stotra

Once you confirm the exact name, I can help with the correct text and meaning respectfully.
