Zohar 2:20a

Jewish Mysticism
Rabbi Shimon said, woe to those creatures who do not take heed and do not know that at the time when it arose in thought before the Holy One, blessed be He, to create His world, all of the worlds arose in a single thought, and with this thought they were all created, thus it is written, “[How great are your works, oh Lord], you have created them all with wisdom…” (Psalms, 104-24). And with this thought, which is wisdom, was created this world and the world above. He cast forth His right hand and created the world above. He cast forth his left hand and created this world. Thus it is written, “Even my hands have established the earth, and my right had has stretched forth the heavens; when I call to them, they stand together” (Isaiah, 48-13). All of them were created at one moment. And He created this world to correspond to the world above, and everything that is above, such is its image below.
