Likutei Moharan 64:1/ליקוטי מוהר"ן ס״ד:א׳

1God said to Moshe, “Bo el Paroh (Go to Pharaoh), for I have hardened his heart and the heart of his servants, that I might set these signs of Mine in their midst; and that you might recount in the ears of your children and your grandchildren how I have made a mockery of the Egyptians, and of My signs which I have wrought in their midst—that you might know that I am God.” [Moshe and Aharon went to Pharaoh, and they said to him, “Thus says God,] ‘… tomorrow I will bring locusts into your borders.’” (Exodus 10:1-4)

2God created the world as a consequence of His compassion. For He wanted to reveal His compassion, and if Creation had not taken place, to whom would He have shown His compassion? He therefore created the entire creation, from the inception of Atzilut all the way down to the center point of the corporeal world, in order to display His compassion.

3Yet when God wanted to create the world, there was no place in which to create it, since there was nothing but Ein Sof (the Infinite One). He therefore contracted the Light to the sides, and through this contraction the Vacated Space was made. Then, within this Vacated Space, all time and space came into existence—this being the creation of the world {as explained at the beginning of Etz Chaim} .

4This Vacated Space was necessary for the creation of the world, since without the Vacated Space there would have been no place in which to create the world, as explained above. Yet, understanding and comprehending this contraction [that resulted in the formation] of the Vacated Space will be possible only in the Future, since it is necessary to say about it two contradictory things: existence and nonexistence.

5The Vacated Space is the result of the contraction; that [God], so to speak, withdrew His Godliness from that place. Thus there is, so to speak, no Godliness there. Were it not so, it would not be vacated. There would then be nothing but Ein Sof, with no place whatsoever for the world’s creation. However the actual truth is that, even so, there is surely Godliness there as well. For there is surely nothing without His life-force. This is why it is not at all possible to comprehend the concept of the Vacated Space until the Future.
