Panchadashi 1.16

Due to the purity of sattva in that Prakriti, it is called maayaa. Due to the impurity of sattva, that Prakriti is called "lack of science" or avidyaa. The source of the reflection, lying in maayaa, is controlling that maayaa, and for that reason, has become the omniscient Ishvara.

There is purity in the enlightened sattva property. When this sattva property does not get tainted with other properties, then that Prakriti is called "maayaa". When that Prakriti becomes tainted with the other properties, it is called "lack of science". In brief, pure-sattva-dominant Prakriti is called "maayaa", and impure-sattva-dominant Prakriti is called "lack of science".

That self reflected in maayaa has made maayaa subservient, and that omniscient one alone has become the Ishvara with properties (gunaas).
