זוהר בראשית — דף ריה ע”א

Rabbi Shimon said: a person's faith rests on three things: truth, peace, and justice. When these three are united, the Shekhinah dwells. The Throne is the Shekhinah, and it is called the Throne of Glory because it carries the Glory upward. Whoever serves the sages is like a friend of the King, and his joy is great.
