Accordingly the light, which is from the Eyn Sof, blessed be He, must also wait until the vessel is completed, since this is where the root of evil lies. Only afterwards will it shine in it... This is for the reason I have explained, for this is the proper order. For it was the Tzimtzum that was an innovation, while Eyn Sof wanted to reveal His prior existence – to make it known that this innovation was only a concealment which He desired in order to demonstrate His very perfection, as already discussed in various places. It was therefore necessary to wait until the Tzimtzum carried out its function, and then go to return everything to His unity, and through all of this to show His perfection.
