This is quite simple, for the pathway of limitation was conceived by Eyn Sof, except that at the level on which He conceived it, it was beyond limits and boundaries because His intrinsic limitlessness held sway and brought it back to His level, which is beyond limitations. However, when Eyn Sof, blessed be He, removed His limitlessness from it, it remained as He conceived it prior to the removal of His limitlessness, except that now it was an actual creation as opposed to a hypothetical possibility. Thus, prior to the Tzimtzum, the Sefirot were included in Eyn Sof – which is the first inference made above. However, on that level they existed not in the way they exist now but in a different way, which is the way of limitlessness. This is the second inference made above.
