Answer: Both the First and Second Temples were destroyed so that the Jews could be dispersed among the nations of the world; they laid the makings of certain elements of connection with the upper force of nature and with the completion of their development, starting at the end of the 20th century, started their elevation. It is said that the Jews went into exile in order to collect the souls of the nations of the world.
Both Temples symbolized the achievement of a very high level of the spiritual Light, the level of Haya, and the Second Temple symbolized the level of Neshama (soul).
Afterward, the Jews had to “fall and dissolve” within the nations of the world. Also under the concept of “the nations of the world,” the meaning isn’t what we usually imagine, because according to the spiritual roots, there are only 70 nations of the world, and the Jews had to be dispersed and assimilate among them. It was stated that at the end of the 20th century, the general correction of the world would begin, realized first with the nation of Israel and then gradually joined by the rest of the nations.
