But the truth is that it is only a certain level of the primordial light, whose power was reduced through the Tzimtzum. For the way of bounds and limits was originally subsumed within Eyn Sof, blessed be He, only His aspect of limitlessness caused the light to expand beyond all limits. When the aspect of limitlessness was removed from it, it remained with its limited power. If so, the light is from the very essence of Eyn Sof, but the Tzimtzum reduced and limited its power.
In the prophetic vision, the way in which this appears is that a new light – the light of the Reshimu, the “Residue” – was generated from the concealed Source – Eyn Sof.
