The worlds developed [nishtalshelu] until this material world came into being, a place that contains both body and soul, and a time wherein both corruption and repair are possible. The body, which is the desire to receive, derived from its roots in God’s plan for creation, as discussed earlier. But it [the body] passed through the worlds of impurity, as Job states: “A wild ass gives birth to a human” (Job 11:12). [The words “wild ass” refer to the worlds of impurity.] It [the body] remains enslaved under that system until age thirteen. That is the period of corruption.
