There is Israel in the inner sense (Isra-El, Yashar Kel, straight to the Creator), which is a person with a point in the heart or one who aspires to spirituality. Besides, there is an external meaning to the nation of Israel. However, they also aren’t just people, but souls who were chosen in Ancient Babylon by the force called Abraham (the force of Hesed, bestowal) out of the general breakage called “the Babylonian confusion.”
Back then this confusion took place on the first degree of desire and it was from there (from Babylon) that Abraham chose these desires, which desired to correct themselves. Later they attained the level of Mochin de Haya – the First Temple, meaning that they already ascended to the level of AB and SAG, and then broke.
Now these Kelim are included in the general desire and it’s clear that compared to others, they contain a preliminary preparation, which helps them begin to ascend. These Kelim are called Israel in our world.
That is why there is a difference between a person who was born a Jew and one who was not born a Jew but who belongs to Israel by virtue of his point in the heart. A person who was born part of Israel probably has an inclination to ascend inherent from the previous breakage.
However, if a person does not belong to the nation of Israel by birth, it is unknown who he is because we do not know where the ten lost tribes of Israel are located, as they were dispersed after the breaking of the First Temple. They did not take part in building the Second Temple and therefore did not reach “unfounded hatred,” which was the reason for its destruction. They only went through the first breakage, not being able to “receive for the sake of bestowal.” However, it’s as if they kept the degree of “bestowal for the sake of bestowal” in an unbroken state!
That is to say, now as we ascend from below upwards and attain the level of “bestowal for the sake of bestowal” in the general mass, we will reveal the ten lost tribes! We will attain equivalence of form with them and then they will be found.
