Kabbalah su Salmi 24:3

Rabbi Abba opened the discussion with the text, "Who shall ascend into the mountain of Hashem? Or who shall stand in His holy place?" (Tehilim 24:3). Come and behold, no man is aware of the reason for his existence in the world. As the days pass by they rise up and stand before the Holy One, blessed be He, as they were all created. How do we know that they were created? Because it is written, "The days were created" (Tehilim 139:16).
