Creation:

When His will arose to create the worlds there was no place, for the unbound light filled all that was. 

To create the worlds He constricted His unbound light from the center point within Him outward, and an empty space in the shape of a circle was formed, with the light around it.

Then, into the round space He drew a line of light with which He created, formed and fashioned all the worlds.

(according to Ha’Ari)
