I’m not fully recognizing the exact sutra from the wording “Sadhaktya devloke sutra.”

It might be:

• A mis-heard / mis-written line from a Jain stotra or sutra, or
• A local / oral variation used in some upāśray/derāsar, not a standard textual title.

To help you properly, I need a bit more detail from you, for example:

• Any full line where this comes (even if approximate)
• The context: is it from a daily pākṣik / pratikraman, a vandan, a stavan, or something you hear in gyan–sabha?
• Language you heard it in (Sanskrit / Prakrit / Gujarati / Hindi, etc.)

Without that, if I guess, I might distort the original Jain meaning, which I must avoid.

If you can type 1–2 more words around “sadhaktya devloke” (previous or next line as you remember), I can usually identify the correct sutra/stotra and then:

• Give you the correct original text,
• Give a simple, authentic Jain meaning (arth),
• Mention if there is any difference in use/meaning in Śvetāmbara / Digambara tradition.
