Question: We say that the Temple is “located” in the human heart. What does that mean?
Answer: The Temple is the center of the connection of the people. It teaches us to unite and contains the properties that demonstrate how everything should be realized.
Why do we use the phrase “destruction of the Temple” instead of saying the “destruction of the country?” We say it because the Temple was a spiritual basis, a place where the unification process had stopped. It took place seventy (70) years before the Temple was destroyed.
Seventy (70) years stand for 7 Sefirot, 10 years in each Sefira. The Nation gradually descended these steps until it reached Malchut: Hesed, Gevura, Tifferet, Netzach, Hod, Yesod, and Malchut… Here the destruction of the Temple (shattering of unity) occurred. It was known well in advance.
It means that people stopped bringing genuine sacrifices to the Temple, meaning the ones that lead to unity. They started to emphasize: “It was I who made a sacrifice.” The “I” (our egoism) is something that interferes and destroys all Temples. It’s the cause of destruction.
