Zohar 2:142b

Jewish Mysticism
When the spirit ascends to be crowned within the supernal soul above, the breath is bound within the spirit and is illuminated from it like the moon when it is illuminated by the sun. The spirit is bound within the soul, and the soul is bound within the End of Thought, which is the mystery of the supernal soul. The breath is bound within the supernal spirit, and the spirit is connected within the supernal soul, and the soul is connected in ein sof, and thus, it is the comfort of all and the bond of all above and below, all in one mystery and one manner.
