Here are simple, authentic Jain mantras you can chant in the evening. Start with Navkār Mantra, then do forgiveness (Kṣamāpanā). If you have more time, add a short stotra.

1) Navkār Mantra (universal in all Jain traditions)

• Text (Prākrit):

Namo Arihantāṇaṁ Namo Siddhāṇaṁ Namo Āyariyāṇaṁ Namo Uvajjhāyāṇaṁ Namo Loe Savva Sāhūṇaṁ Eso paṁca namokkāro, savva-pāvappaṇāsano; Maṅgalaṇaṁ ca savvesiṁ, paḍhamaṁ havai maṅgalaṁ.

• Simple meaning:

I bow to Arihants, Siddhas, Āchāryas, Upādhyāyas, and all Sādhus. This five-fold bow destroys sins and is the highest auspiciousness.

How to use: Sit calmly, focus on breath, and chant the Navkār 9, 27, or 108 times.

2) Evening forgiveness prayer (Kṣamāpanā)

• Text:

Khamemi savva jīvā, savve jīvā khamantu me; mittī me savva bhūesu, veraṁ majjha na keṇai.

• Meaning:

I forgive all living beings, may all beings forgive me. I am friendly to all, I have enmity toward none.

How to use: Recite slowly 3–5 times, remembering anyone you may have hurt and sincerely letting go.

3) Optional short stotras (choose any one, as per your tradition)

• Uvāsaggaharama Stotra (for removal of obstacles; Shvetāmbara usage common).
• Bhaktāmar Stotra (any 1–3 verses with devotion).
• Logassa Sutta (Digambara tradition; often recited daily).

Tradition note:

• Both Digambara and Shvetāmbara recite the Navkār Mantra and the forgiveness prayer.
• Specific stotras in the evening vary: Digambara families often include Logassa; Shvetāmbara families often include Uvāsaggaharama and Pratikraman sutras.

Simple evening flow (10–15 minutes):

• Quiet sitting (1 minute)
• Navkār Mantra (9 or 27 times)
• Kṣamāpanā prayer (3–5 times)
• One short stotra (optional)
• End with peaceful silence (1 minute)

May this practice bring śānti (peace), saṁyama (self-restraint), and maitri (friendliness) to all beings.
