Answer-

The word Maya comes from the ancient Indian/Hindu Sanskrit language (...as in Sub-continent India not native American Indian :-)

* The power of a god or demon to transform a concept into an element of the sensible world.

* The transitory, manifold appearance of the sensible world, which obscures the undifferentiated spiritual reality from which it originates; the illusory appearance of the sensible world.

*Maya – the illusion of the manifested world

P.S- Maya 3d software name has nothing to do with the South American Maya civilization.
