“Once, two great people were speaking.
One said, “I have reached the seventh heaven!”
The other replied, “I am so small that the seventh heaven comes down to me.”
No one is great enough to reach the heavens.
Indeed, the greater a person is the more he prevents the heavens from descending to him.
However, when a person is small, the heavens can reach him.”
From Understanding the Tanya, p. 11 by Rabbi Adin Steinsaltz
