In Jainism, “limit gyan” usually refers to Avadhi Jñāna.

• Avadhi Jñāna is discussed in Tattvārtha Sūtra and also in Bhagavatī Sūtra and other Āgamic texts.
• “Swar vigyan” is not a standard Jain scriptural term like Avadhi Jñāna. If you mean shabda/svara related knowledge, that is generally discussed in a broader philosophical sense, not as a separate named Jain doctrine.

So, if you mean limit gyan = Avadhi Jñāna, then the main Jain scripture is Tattvārtha Sūtra.
