Zohar 1:60b

Jewish Mysticism
The desire of the female towards the male occurs only when a spirit enters into her and casts fluid corresponding to the supernal, masculine waters. Analogously, the Community of Israel is not aroused in relation to the Holy One, blessed be He, except by means of the spirit of the righteous who enter into her.
