זוהר בראשית — דף קפד ע”ב

The Zohar explains that there are two levels, the blessed and the cursed: from one come the blessings and redemption, from the other the curses, the sword and desolation. Rabbi Shimon opens with “I will wash my hands in innocence”: at night the holy soul departs and a spirit of impurity rests on the body; therefore in the morning one washes the hands with a vessel, does not pass a hand over the eye, and does not bless until the defilement has passed. The water of this washing is impure: it should not be poured out in the house but in a place where people do not pass, and it should not be given to sorceresses. On “they took him and cast him into the pit,” Rabbi Yehuda opens with “The Torah of the Lord is perfect”: one who engages in Torah for its own sake merits long life in the world to come and a good reward in this world.
