CRAIG: Is masturbation a sin?CRAIG: Why?
Rabbi: Masturbation is forbidden according to Jewish law
Rabbi: Kabbalah is very explicit about the negative spiritual side-effects of masturbation. The idea is as follows: Your seed is the material by which you procreate; it is the genetic material within you that allows you the opportunity to partner with G-d.When we let human seed go to waste, we squander G-ds sacred and divine potentialCRAIG: Hows that?
Rabbi: When we use it constructively, we channel the Divine sparks and energy within it correctly, and it comes to good use within the world via children who in turn will produce more children, in this way continuing the path of humanity. When we let it go to waste, however, we squander G-ds sacred and divine potential. (This allows for what Kabbalah calls Chitzonim, negative forces loosely translated as outsiders, to snatch the energy and convert it for negative purposes.)
This rabbi is misrepresenting the facts. Kaballah is a mystical practice based on a certain body of writings that, as far as I know, is not accepted as authoritative by any of the main branches of Judaism. This is a Jewish view of masturbation, not the Jewish view, at least as far its basis in kaballah is concerned. Maybe there is a basis for it in the Talmud or the responsa literature, but this rabbi's argument doesn't show that.
