As you find God, you lose your individual identity. with the loss of individual identity your soul is made pure. In this state of purity you lose your personal attributes. As you lose your personal attributes, you become wholly present to God. By being wholly present to God, you are wholly lost to the self. When God first overwhelms you by manifesting himself, you are bewildered - as if drunk. But as you lose the self, you have the clarity of sobriety. You see all things as they are, and you know their place and qualities.
