Zohar, Bereshit 1

1With the beginning of the manifestation of the King's will, that is, when the King desired to emanate and create the world, a hard spark made an engraving upon the supernal light. This hard spark, which emanated from the most concealed of all concealed things from the secret of the Endlessness Light took a shapeless form. The spark was then inserted into the center of a circle that was neither white nor black nor red nor green, nor any color at all. When it began its measurements, it created colors that shone into the empty space and the engraving. From within the spark - This hard spark - a fountain spouted, from which the shades down below received their colors.

2From the most concealed of all concealed things, from the secret of the Endlessness Light, emanated two faces: One cleaved and the other did not cleave. Its atmosphere was unknown until forceful blows split Atik, and a concealed supernal point shone. Beyond this point, nothing is knowable and, because of this, it is called by the name Beginning, which means the first of the sayings.
