925. "The hooks of the pillars and their joints shall be of silver" (Shemot 27:10). Rabbi Yitzchak said, "The hooks of the pillars:" I say all these that are joined with the forms of the supernal pillars, WHICH ARE NETZACH AND HOD, are called 'the hooks of the pillars.' All those of below are suspended from these hooks. What are hooks (Heb. vavim)? They are six within six, BECAUSE VAVIM (VAV'S) ARE TWO TIMES SIX (=VAV), FOR THE SIX EXTREMITIES ARE COMBINED OF EACH OTHER AND EACH ONE HAS SIX. THEREFORE, NETZACH IS SIX AND HOD IS SIX. They are united and watered by the spinal column, WHICH IS TIFERET that stands over them, FOR TIFERET STANDS OVER NETZACH AND HOD. In Safra De'tzniuta (Eng. 'the hidden book'), we learned that there are Vav's above, IN CHESED, GVURAH AND TIFERET, and Vav's below, IN NETZACH, HOD AND YESOD. They all are interpreted in the same way, MEANING THAT THERE IS NO DISPUTE HERE.
