Navkarsi (Namokar Mantra) is the fivefold salutation at the heart of Jain practice. Here’s a simple way to understand and practice it.

What you chant (Prakrit lines)

• Namo Arihantanam
• Namo Siddhanam
• Namo Ayariyanam
• Namo Ujjhayaṇam (Digambar: Ujjhāyaṇaṁ)
• Namo Loe Savva-sahuṇam
• Eso pancha namokāro
• Savva-pāvappaṇāso
• Maṅgalānaṁ ca Savvesim
• Padhamam havai mangalam

Essence (arth)

• Bow to the five guṇa of the enlightened beings: Arihants, Siddhas, Āchāryas, Upādhyāyas, and all Sādhu/Sādhinīs.
• The mantra purifies, helps remove karmic obstacles, and is the foremost auspicious chant.

Simple practice steps

• Posture: Sit in a calm, respectful posture before darshan or study.
• Pronunciation: Recite slowly with understanding of each line and the meaning.
• Rhythm: Many chant 9, 27, or 108 repetitions, daily or before prayer, meditation, or study.
• Attitude: Maintain ahimsa (non-violence), truth, and a mindset of purification, not asking for worldly favors.

Notes

• The meaning and core structure are the same in both Digambar and Shwetambar traditions, though minor word forms or order can vary a little in different communities.
• After the Navkar Mantra, practitioners often perform darshan with a focus on right faith, right knowledge, and right conduct.
