Namaste Akilesh ji.
This is a very relevant point.
Singular inactive entity cannot accomodate diverse appearances.
Clay/pot examples are given pariNAma-vAda as the framework.
That is initial teaching which is sublated and vivarta-vAda is taught. That is rope-snake example.
So, a non-existent illusory ignorance is admitted which then solves the issue of diverse appearances despite there being singular inactive reality.
Subsequently, even the vivarta-vAda is sublated and ajAti-vAda is taught which is the frame of reference of substratum hence there has never been any appearance.
