From the discussion in this and the previous Openings, you should understand that there are three aspects to the Sefirot: (1) the vessels; (2) the mental powers; (3) the inner and encompassing lights. The vessels are the different levels of the Residue – the laws that exist after the concealment of perfection. Through the inner and encompassing lights, Eyn Sof is found on all the different levels. The mental powers are the garments (of the Line) and are made to suit each Partzuf depending on what it is. It is through these mental powers that Eyn Sof, blessed be He, connects with and governs each one according to its particular nature, as discussed above.
