Thus we are saying that by clothing itself in Arich Anpin, Atik Yomin strengthens Arich in the aspect of Balance. This would not have come about through the chain of development (because in terms of where it emerges, Atzilut is the radiance of the face of Adam Kadmon). One unique power is needed to bring the various aspects of Arich Anpin under the repair effected through the Balance. (The function of Atik Yomin is to bind the government of Arich Anpin, which is conducted through the Partzufim of Atzilut, under the rule of Adam Kadmon. Atik Yomin thus serves as the link between the World of Work – Atzilut – and the World of Reward – Adam Kadmon.)
