This passage opened my eyes. It is a necessary confrontation with the human mind that is addicted to justifying itself in sequential time/space. This habit is only a delaying tactic to avoid the inevitable realization of the present Truth of our eternal Self. Simply by allowing this confrontation to occur, and not defending against it, a change happens....the Way opens spontaneously, through grace. The sudden shift is referred to as a miracle. This beautiful transmission is from the "Advaita Vedanta of the West"...the  non-dual teaching of Christ consciousness, transmitted from the enlightened mind of Jeshua (Jesus), called A Course in Miracles. It is the "Yoga of the Christ."  It is a springboard to the immediate experience of enlightenment...which is "a simple recognition, not a change at all."  Enter into this universal experience with me now, be reunited and realize the ever-present, limitless peace that is your natural inheritance...En
"Why wait for Heaven? Those who seek the light are merely covering their eyes. The light is in them now. Enlightenment is but a recognition, not a change at all. Light is not of the world, yet you who bear the light in you are alien here as well. The light came with you from your native home, and stayed with you because it is your own. It is the only thing you bring with you from Him Who is your Source. It shines in you because it lights your home, and leads you back to where it came from and you are at home.

This light can not be lost. Why wait to find it in the future, or believe it has been lost already, or was never there? It can so easily be looked upon that arguments which prove it is not there become ridiculous. Who can deny the presence of what he beholds in him? It is not difficult to look within, for there all vision starts. There is no sight, be it of dreams or from a truer Source, that is not but the shadow of the seen through inward vision. There perception starts, and there it ends. It has no source but this."
