Jai Sai Master!
Shirdi Sai, in HIS inimitable ways, taught this in very simple terms. HE never was one to talk of words like Brahman, Maya etc.. Instead, HE taught people how one can feel the GOD in everything around - The omnipresence.
(from Sri Sai Leelamrutam - written by Pujya Acharya Sri Ekkirala Bharadwaja)
Proving existence of something that is not seen is a very difficult task and particularly when we talk about the ULTIMATE TRUTH. Only the realised souls have the real feel of the same and they say, it is a matter of experience rather than simple explanation, about that state. It is a like current flowing in the wire which helps to light the bulb, which is unseen but exists, when tested. There is no denial of the fact, especially, in this side of the world about that ULTIMATE TRUTH.
