ONE PILLAR extends from earth to heaven. Its name is Righteous One, named for the righteous. If there are righteous people in the world, the pillar is strengthened; if not, it is weakened. It upholds the entire world, as it is written: “The righteous one is the foundation of the world.” If it weakens, the world cannot endure. So if the world contains just one righteous person, that person sustains the world.
