The Book of Zohar, “Night of the Bride”: All the days of exile are called night, for this is when the Creator’s face is concealed from Israel, as the impure forces rule and separate His loyal servants from Him. Yet, this is the time when the bride unites with her husband…
The union between the bride and her husband (The Zohar uses the word “husband” instead of “bridegroom”) occurs thanks to the Torah and Mitzvot (Commandments) of the righteous, referred to as “those who keep the Torah…”
The point in the heart, the spiritual awakening during the long exile—which means in the duration of six thousand years—grows only by darkness, by the feeling of exile. We must turn this darkness into Light each time until, after the six days of action, we reach the seventh day of the seventh millennium, a state of total Light.
Therefore, all of our work is to accept the state as darkness, as night, and turn it into day. We determine that the state, the feeling we have received, is day and not night.
It seems as darkness with regard to our ego, with regard to the desire to enjoy, and with regard to our desire to bestow it seems as an opportunity and as Light.
