THE ESSENCE of serving God and of all the mitsvot is to attain the state of humility, that is, to understand that all your physical and mental powers and your essential being depend on the divine elements within. You are simply a channel for the divine attributes. You attain this humility through the awe of God’s vastness, through realizing that “there is no place empty of it.” Then you come to the state of Ayin, the state of humility. You have no independent self and are contained in the Creator. This is the meaning of the verse: “Moses hid his face, for he was in awe.” Through his experience of awe, Moses attained the hiding of his face, that is, he perceived no independent self. Everything was part of divinity.
