Aath Koti Nani Paksha is not a universal Jain doctrine. It is a name used by certain local Jain sanghs/sthanaks (places of worship) in India, notably in regions like Kutch and Mumbai. Break here:

• Aath = eight
• Koti = crore (a large number)
• Nani Paksha = a specific “Nani” faction/sect within Jain tradition that runs these local sanghs

So “Aath Koti Nani Paksha” literally means the “Eight-Crore Nani-Faction” and is mostly the designation of a particular community-sangh (not a para with new Jain scriptures) that runs a sthanak or temple and organizes events, prayers, and rituals.

Key point to understand:

• This term appears as the name of local Jain communities or sthanaks (not as a separate, independent Jain philosophy). Different places may have their own Aath Koti Nani Paksha sangh with similar naming but slightly different local practices.
