The upper light that is drawn from Ein Sof and given in the partzufim, after the constriction (tzimtzum) and onwards. It is called by this name to indicate that it is not given in the > of the circular sefirot. The same applies to all levels that contain nothing of the opacity (ovyut) of the fourth level, except for the sefirot of the straight line alone. This is in accordance with the general rule that one who bestows does so only in something that is more opaque, which is the opacity (ovyut) of the fourth level (Talmud Eser Sefirot, v. 2, Q & A 3).
