“Satlakh” (सतलाख/સતલાખ) in Jain practice is not the name of a canonical sutra. It means a devotional anushthan (saṅkalpa) of reciting a chosen Jain mantra or stotra 7,00,000 times. The most common is Navkar Satlakhi (reciting the Navkar/Namokar Mantra 7 lakh times). Some devotees also undertake Satlakhi for other revered stavans or mantras, but these are devotional practices, not Agamic texts.

What people usually mean by “Satlakh Jain sutra written” is the text of the mantra used for Satlakhi. The standard and universally accepted choice is the Navkar (Namokar) Mantra. Original text (Prakrit) and simple arth are given below.

Navkar (Namokar) Mantra — original text

• णमो अरिहंताणं।
• णमो सिद्धाणं।
• णमो आयरियाणं।
• णमो उवज्झायाणं।
• णमो लोए सव्वसाहूणं।
• एसो पंच णमोक्कारो, सव्वपावप्पणासणो।
• मंगलाणं च सव्वेसिं, पढमं हवइ मंगलं॥

Arth (simple, traditional meaning)

• I bow to the Arihants (perfected beings who have destroyed inner enemies like anger, pride, deceit, greed).
• I bow to the Siddhas (liberated souls).
• I bow to the Acharyas (heads of the Jain order).
• I bow to the Upadhyayas (spiritual teachers).
• I bow to all Sadhus/Sadhvis (monks and nuns).
• This five-fold bowing destroys all karmic sins and is the foremost among all auspicious things.

Notes on traditions

• Both Śvetāmbara and Digambara accept the Navkar Mantra. Pronunciation may vary slightly (e.g., “Ayariyāṇam/Āyariyāṇam”), but meaning and reverence are the same.
• “Satlakhi” itself is a vrata/anushthan of counting recitations; it is not a separate sutra in either tradition.

If your Satlakhi is for Navkar Mantra, you can use the above text exactly and keep a japa count until 7,00,000 is completed with śraddhā, careful pronunciation, and ahiṁsā-bhāva.
