Thus we have here three aspects: (1) Eyn Sof’s action in His intrinsic perfection – executing the very things that we receive within limits. (2) What we receive, as we receive it, within limits. (3) The way the All-Powerful looks down to the level of limits and boundaries whereby we receive. The way the All-Powerful looks down to the level of limitations is through this Channel, which is also a Line from Eyn Sof, blessed be He. Through it He looks down into the Residue and watches over it in accordance with the nature of the Residue, which is within limits. What we receive (#2) is the totality of the Residue. The very thing that Eyn Sof, blessed be He, executes in His perfection (#1) is drawn down from Eyn Sof, blessed be He, into the cavity by way of (#3) the Channel or Pipe.
