Here is a revered Jain verse that helps focus the mind and conquer inner enemies (vasanas/vices) through purification of the soul:

Verse (Navkar Mantra, simple form): Namo Arihantanam Namo Siddhanam Namo Ayariyanam Namo Ulhavayanam Namo Jinam Namu Mahamor” (or sometimes extended with the remaining names)

Arth (meaning) in Jain context:

• Namo Arihantanam: I bow to the Arihants, those who have conquered inner enemies and attained kevala jnana with complete self-control.
• Namo Siddhanam: I bow to the Siddhas, liberated souls who have burned away all karmic bonds.
• Namo Ayariyanam: I bow to the Acharyas and spiritual guides who lead seekers on the path.
• Namo Ulhavanam (Uravayānanam/Ulbhavaayanam in some traditions): I bow to those who protect and sustain the right path and communities.
• Namo Jinam: I bow to the Jinas (Conquerors) who show the path to liberation.
• Namu Mahamor: I bow to the great beings who destroy delusion and guide us toward moral purity.

How this helps against inner enemies:

• The verse is a reminder to revere the enlightened beings who have conquered inner passions (krodha, lobha, moha, matsarya) and to align one’s thoughts, speech, and actions with non-violence, truth, and self-discipline.
• Regular recitation or reflection on these names fosters humility, detachment (virag), and steadfastness in ethical vows, reducing the grip of ego, anger, greed, and attachment.

Notes on tradition:

• The core meaning is shared across Digambar and Śvetāmbara traditions, though exact pronunciations and order can vary slightly in different lineages.
• If you’d like, I can provide the precise Sanskrit text in the form used by a specific tradition (Digambar or Śvetāmbara) and explain any small variations.

Would you like me to give you the exact conventional Sanskrit wording for a particular Jain tradition and a brief word-for-word translation?
