That which you speak of is what you are. It is not possible to speak of anything outside of you or your perceptions.

If you speak of ego, then that is your truth. There is no question that ego is in play. It is smart to disregard everything this person says.

If you speak of God, then that too is truth. However, there has to be some proof, some other way of detecting honesty. Too many times have these words been spoken to the detriment of man and mankind.

While it is not smart to believe every one who says, "I AM God," it is also not necessary to automatically crucify or kill those who do.
