It is in Adam Kadmon that the connection of the Line with the Residue which it took as its vessel was brought about. Thus the light emerging by way of the senses is light that is already joined with the vessel, which is why it afterwards brings forth the vessel through the lights of the mouth. This alone is the light suitable for the construction of all the structures built out of it, and that which was necessary to build all the intended structures went forth and unfolded gradually in stages as necessary to serve the intended purpose of these structures.
