Acharya Padvi is not a separate doctrinal term in Jainism by itself. It combines two words:

• Acharya: the head or supreme spiritual leader of a Jain monastic order (the head of a samiti).
• Padvi: a word meaning rank, position, or formal office/appointment.

So “Acharya Padvi” essentially refers to the position or office of an Acharya—the appointed rank of the highest spiritualteacher within a Jain tradition. In practice, it denotes the office of the leading teacher who presides over the monk-assembly and guidance of monks and nuns.

Notes:

• In Jain tradition, the exact customs for appointing and recognizing an Acharya can differ between Digambar and Shwetambar communities, so the emphasis or procedures may vary slightly in each tradition.
• If you’re looking for a scriptural or historical usage of this phrase in a specific text or lineage, tell me which tradition (Digambar or Shwetambar) or which text you have in mind, and I’ll explain more precisely.
