זוהר בראשית — דף רמה ע”ב

The souls of the righteous originate from the higher souls, from the feminine soul and the masculine soul, and therefore they transcend all impure forces. There is a hidden feminine soul within her armies, and the body is the vessel of the soul to perform deeds in the world. The lower world was created in the image of the upper, the upper is hidden and the lower is revealed. The righteous in this world connect the upper worlds by ascending through their deeds and Torah study.
