Yo bro, it's not just an endless recursion of worlds, it's much more than that. If this passage is completely true, it's totally fucked up. Each Sphirah contains in itself all 10 Sefirot arranged in a four-step, spiritual form Kli, i.e. each Sphirah contains in itself the whole world(hierarchy of hierarchies) and each Sphirah in each world contains in itself the whole world, and each of those worlds contains ten Sefirot and in each of them contains the whole world - you can continue until you get bored. That is the infinity degree of infinite hierarchy of worlds within the material universe, that is the lowest rung of hierarchy of worlds of the Tree of Sefirot, that is in fact it is only the beginning of the beginning, there are also other Spheres, which are beyond the material universe. And I'm not even talking about Ohr Ein Sof, and the fact that all these recursions are just a reflection of Ketera, and Ketera is the first world born from the contraction of Infinity, that is, the infinitesimal part of the infinity of Ohr Ein Sof 000, but there are also Ein Sof 00 and Ayin 0. Interestingly, all these infinite recursions at all levels are completely canonical, that is, the original Kaballah also has all these recursions. In short, the original Kaballa is totally fucked up in terms of power levels.
