Ha'azinu: Chapter 42
The mouth of Zeir Anpin
Synopsis

We read that good and evil and life and death depend on the lips of Zeir Anpin. When the lips speak all the watchers awaken to decree punishments. Rabbi Shimon explains what is meant by a 'watcher.' We learn that when words come out of the mouth of Zeir Anpin they illuminate 18,000 worlds.
