Chasidut su I Re 6:38

If you examine the creation account, the first three statements detail spiritual items that do not fully exist in our dimension of reality: “In the beginning,”³⁵⁴The words “and God said” are missing from this statement, because this creative power is the hidden root. With it, God created speech and the incipient forces that would later become material existence (Rav Wolfson). “Let there be light,” and, “Let there be a divider between [spiritual] waters above and the waters below on earth.”³⁵⁵The first statement created an initial existence, one which could not be fully verbalized. This does not exist fully in our world, where items are relatively completed. The second statement created a light that according to our sages was too holy for mere man so it was hidden away for the righteous in the World-to-Come. The third statement created a spiritual barrier that will never be touched by man. The fourth statement, “Let the waters gather and reveal the dry land,” and all the subsequent creative demands deal with the earthly realm. Evidently, in our dimension of reality, God appears through the seven lower Sephiros, and the first three lights are only fully realized in Heavenly worlds.³⁵⁶Later on it is taught that the deeper meaning of seven days of creation is that they refer to the seven lower Sephiros, or the seven revelations of God’s light that animate the seven days of the week—each day has a different revelation. The Temples that stood in Jerusalem and the mobile tabernacle the Jews constructed in the Desert were places that were filled with these seven Lights. That is why Betzalel, who constructed the tabernacle, knew the secrets of creation, because he had to bring down the same influences that fill the physical world (See further Innerspace pg. 57). This is also the meaning of the verse about Solomon’s temple, va-yivnehu sheva shanim, “And he built it seven years” (1 Kings 6:38). It does not say, “he built it for seven years,” rather “he built it seven years,” for the building was a manifestation of the seven emanations that are symbolized with the term, seven years. We mourn for the destruction of Temples of Jerusalem on the ninth of Av. During the subsequent seven weeks, on each Shabbos, we read a different prophecy of consolation. The seven prophecies of consolation correspond to the seven lower Sephiros. During each of those seven weeks, a different Sephirah light appears. Since the Temple was a display of the full seven, re-experiencing the seven Sephiros is a partial rebuilding of the Temple and a consolation for its loss (heard from the Stitchiner Rebbe).
