Even though in the upper realm each ascent involves phases of Pregnancy, Suckling and Mental Powers that also renew the exterior, they do not change the intrinsic law and essence of the Partzuf but rather they are stages in its development. Similarly below, the body does not need to change in order to receive those lights. Indeed, when the Additional Soul enters into man it certainly enters in stages – Pregnancy, Suckling and Mental Powers. However these are influences that man receives without undergoing any changes in his body – the exterior – because they do not change his intrinsic law but only give him greater power.
