In addition, if the first state in the Ein Sof already contains all of the perfections of the third state, it follows that the second and third states must occur, with all of the perfections that are already present there [in the first stage]. That is to say, the first state itself requires that the two competing systems [of the body and soul] must separate in the second stage, so that the body – which exists as a defective desire to receive, damaged by the system of impurity – could then be repaired.
Were it not for the system of the worlds of impurity, we would never possess that desire to receive, and it would therefore be impossible to repair that desire and bring about the third stage, because a person cannot repair what he does not possess. Thus, do not ask how the system of impurity emerges out of the first stage, since the opposite is the case. The first stage requires the existence [of the system of impurity] in the second stage.
