Answer

The line:

“सव्वे भावे जम्हा पच्चक्खाई परे त्ति णादूणं।”

is traditionally associated with Jain Prakrit scriptural literature, but I cannot confidently identify the exact Śāstra from this single line alone without a verified textual reference.

Explanation

This appears to be an Ardhamāgadhī/Jain Prakrit gāthā-style line. The words suggest a Jain doctrinal context:

• सव्वे भावे — all states/substances/mental dispositions
• पच्चक्खाई — to renounce / reject / abandon
• परे त्ति णादूणं — knowing them as “other”

The meaning appears connected with the Jain principle of distinguishing the self from non-self and renouncing attachment to all external or non-self states.

Takeaway

Sorry, I can only provide information that is clearly established within Jain tradition. If you can share the full gāthā, surrounding verses, or the book/page where you found it, I can help identify it more accurately.
