God is unfathomable, un-understandable, so is Maya. Maya causes duality. Maya is not duality. So they say, 'Maya is God's shadow'.
You are not sitting here now in reality, although you are in appearance. You are everywhere. But you think you are sitting here. This is false. Who is the creator of this false impression and who gives you this ignorance? Maya. The Soul that is in Maya's ignorance has mind as its medium. You now see what you are. If you look within and experience within, then you know you are the Soul, Infinite—beyond Maya and its creations.
Mind and body are under the sway of Maya. In reality mind and body do not exist—only Soul. When Soul is in Maya's domain, Soul, as it were, becomes the mind; and mind, as it were, becomes the body. So the Soul, through ignorance caused by Maya, thinks itself as mind, or the subtle body, or the gross body.
