Levitico 21:15 Cabala: Reshit Chokhmah

More about one who emits semen in vain, from the words of Rabbi Shimon Bar Yochai of blessed memory (Zohar Emor): 33. He continued with the verse, “Neither shall he profane his seed among his people, for I Hashem do sanctify him”(Vayikra 21:15). Come and see, whoever ejaculates semen in vain is not worthy of beholding the face of the Shechinah, and is considered evil, as written, “For You are not an El that has pleasure in wickedness; nor shall evil dwell with You” (Tehilim 5:5). THIS REFERS TO one who emits it by hand or through another, unworthy woman. You may argue that one who ejaculates it within a woman who does not conceive IS also CONSIDERED TO BE EMITTING SEMEN IN VAIN. This is not so, but only those we mentioned. 34. A man should therefore ask the Holy One, blessed be He, to summon him a worthy vessel, THAT IS A WORTHY WOMAN, so as not to blemish his seed. Whoever ejaculates his seed in an unworthy vessel blemishes his seed. Woe to him who causes damage in his seed. And if this is true for other people, it is much more so to a priest that is below, CORRESPONDING to a likeness of above in utmost holiness. IT IS THEREFORE WRITTEN, “NEITHER SHALL HE PROFANE HIS SEED AMONG HIS PEOPLE.”
