What are we?
The greater you are, the more you need to search for your self. Your deep soul hides itself from consciousness. So you need to increase aloneness, elevation of thinking, penetration of thought, liberation of mind—until finally your soul reveals itself to you, spangling a few sparkles of her lights. Then you find bliss, transcending all humiliations or anything that happens, by attaining equanimity, by becoming one with everything that happens, by reducing yourself so extremely that you nullify your individual, imaginary form, that you nullify existence in the depth of your self. “What are we?” Then you know every spark of truth, every bolt of integrity flashing anywhere. Then you gather everything, without hatred, jealousy, or rivalry. The light of peace and a fierce boldness manifest in you. The splendor of compassion and the glory of love shine through you. The desire to act and work, the passion to create and to restore yourself, the yearning for silence and for the inner shout of joy—these all band together in your spirit, and you become holy.

Think of yourself as Ayin and forget yourself totally. Then you can transcend time, rising to the world of thought, where all is equal: life and death, ocean and dry land. Such is not the case if you are attached to the material nature of this world. If you think of yourself as something, then God cannot clothe himself in you, for God is infinite. No vessel can contain God unless you think of yourself as Ayin.
Effacement
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.

So there is a joke you probably know on the topic of humility. The chief rabbi of the synagogue at Yom Kippur is beating his breast and crying, tears running down his cheeks “I’m nothing, Lord! I’m nothing! I’m absolutely nothing!” Next to him the chief donor to the synagogue, a wealthy banker kneels down and hits himself on the chest and yells “I’m nothing! God forgive me for thinking I’m something. I’m not. I’m nothing!” Whereupon Shlomo a poor man who sweeps the synagogue out after services and halls trash gets down on his knees and yells “I’m nothing! I’m nothing.” The rabbi observes this, elbows the banker and whispers “Look who thinks he’s nothing.”
