Pudgalsar is not a standard or well-known term in Jain scriptures. It may be a mishearing or a variant of:

• Pudgala (पुद्गल): meaning matter or physical substance. In Jain philosophy, Pudgala is one of the five dravyas (eternal substances) alongside Jiva (living beings), Dharma, Adharma, and Akasha (space).

If you meant Pudgala, its basic idea is: matter that makes up the physical world, distinct from the soul (jiva) and the other substances.

If you have a specific text or line where you saw “Pudgalsar,” share a bit more context and I’ll help clarify based on Jain sources.
