Kabbalah zu Jeschijahu 14:29

In a similar way, the Holy One, blessed be He, created the body from the four elements namely, Fire, Air, Earth and Water, which correspond to the Neshamah of Neshamah, the Neshamah, the Ruach, and the Nefesh. Water which is the aspect of the male refers to the sweet waters of holiness. The contrasting bitter waters represent the Evil Inclination. The holy fire which is the aspect of the female. There is the foreign fire, to which the words "that he come not at all times to the holy place" (Vayikra 16:2) apply. And this is the female of the Evil Inclination. The holy Ruach is the aspect of the Male, similar to the Ruach that comes from the Sefirah of Da'at. The unholy Ruach, which is the Evil Inclination. As it is written, "for out of the serpent's root shall come forth a viper" (Isaiah 14:29). There is holy Earth, similar to the Nefesh that comes from the left side of Da'at. And in contrast, there is an Unholy Earth.
