speaking about Presence vs from Presence

"All the great spiritual teachers throughout history were mystics, and the source of their awareness of spiritual truth was the result of Enlightenment and the transformational Realization of the Reality of Divinity as the subjective knowingness that ensues from advanced consciousness by virtue of being at One with the Known. Thus, the Avatar does not speak from knowing "about" but from the actual Presence within, which radiates forth and constitutes the Essence of that which replaces the mind as the source of understanding and Knowingness (the classic Purusha). The process whereby this transformation occurs has been described in the history of each saint, sage, and divine teacher and is often included in the scripture itself."
