Kabbalah zu Bereschit 2:6

Then, “There went up a mist from the earth” {Gen. 2:6}, to make up for the lack, by “watering the whole face of the ground” {ibid.}; and the mist rising is the yearning of the female for the male. Yet another interpretation says that we take the word “not” from the first verse to use in the second with “mist,” and this means that God failed to send rain because a mist had not gone up, for from below must come the impulse to move the power above.
