==== Arich Anpin ====
This is the outer aspect of Keter, and it is the root of worlds. The definition of a world is time and space:

Space is a reality that has six sides: the four directions of the world, up and down - and its root is the six spiritual dimensions: Chesed, Gevurah, Tiferet, Netzach, Hod, Yesod, and Malchut.

Time is a reality of past, present, and future - and its root in spirituality is the attribute of Malchut: melech (king - past), melech (king - present), and yimloch (will reign - future).

The actual existence of midot (emotional attributes) begins in the world of Atzilut, but its root is higher, and it is the level of Arich Anpin. Chassidut compares the difference between the midot in Atzilut and their root in Atik to the difference between a visible flame and the fire within a coal: in a coal, it is not at all apparent that there is fire within it, but when one brings a straw near it or blows on it, a flame emerges, and this is called "concealment that is close to revelation."

The meaning of the name of this level, Arich Anpin, is "large face." Face is the place where a person's inner state is revealed (a person's emotional state, whether he is happy or sad and so forth, is recognizable in his face). The face of the "Man of Atzilut" is called a "small face," and in relation to it, the "face" of the level of Keter is called "large." That is, "Ze'ir Anpin" is the midot of Atzilut in which the mochin (intellect) of Atzilut are revealed, and "Arich Anpin" is the externality of will in which its inner aspect (Atik, the level of pleasure) is revealed.
