Some Light Reading for the Seventh Night of Hanukkah: The Zohar

Rabbi Yitzak said:
The light created by G!d in the act of Creation
flared from one end of the universe to the other
and was hidden away,
reserved for the righteous on the world that is coming,
as it is written —
Light is sown for the righteous (Psalm 97:11)
Then the worlds will be fragrant, and all will be one.
But until the world that is coming arrives,
it is stored and hidden away.
Rabbi Yehudah responded:
If the light were completely hidden,
the world would not exist for even a moment!
Rather, it is hidden and sown like a seed,
giving birth to seeds and fruit.
Thereby is the world sustained.
Every single day, a ray of that light shines into the world,
animating everything;
with that ray G!d feeds the world.
And everywhere Torah is studied at night,
one thread thin ray appears from that hidden light
and flows down upon those absorbed in her.
Since the first day, the light has never been fully revealed,
but is vital to the world,
renewing each day the act of Creation.
