There is a constant pendular movement, between the desire to create and the desire to restrain. This is known as "below and not below." According to the teachings of the Arizal, the first stage in creation was the tzimzum; the contraction of G-d's light to make room for the existence of a finite universe. Gevurah means "strength" or "power," and refers to the forces of contraction and restraint that G d used in creating the world.- As the Mishnah says in Pirkei Avos 4:1: "Who is strong? One who subdues his own nature."- I"
