The sages state that “when the Jews were exiled to Babylonia, the Shekhinah went with them.”
A Hasidic rebbe once said that there are three stages of the exile of the Shekhinah.
The first is the exile of the Jews among the nations.
The second, and harsher, is the exile of the Jews among themselves.
And the third, and most grievous of all, is the exile of an individual within himself.
—Rabbi Adin Steinsaltz
