Knowing about God is a knowledge and knowing God is Realisation of God as "Knowing about something" is different from "knowing something".
Whereas FORM is manifestation of Maya, GOD is FORMLESS that never changes - Nirankar - Changeless in the changing world - He is omnipresent, omnipotent, omniscient and eternal.
God can only be realized with the blessing of living true master.
GOD is the continuum and the world is a super-imposition on this never-changing substratum. We, as limited by five senses, miss the substrate and see what grows over it. Just like we attempt to
see SPACE - we see everything - moon, stars, birds and sky; but fail to see the SPACE.
However our mental ability can make us interpret SPACE and we all see it without seeing it. GOD can be realized in a similar manner. This requires an understanding beyond the five senses,
