זוהר שמות — דף ריו ע”א

The third tikkoun is the rectification of the supernal world with all its armies and camps. The fourth tikkoun is the rectification of prayer in the secret of the holy Name. The fear of Elohim is the fear of the place where judgment resides. There are three colors of fire: the fire that receives fire with joy, the fire in which a radiance is seen, and the fire that surrounds that radiance. In this third fire the fear of judgment begins, and after it love is awakened.
