Kabbalah su Genesi 6:12

Even though this article is talking about the generation of the flood that have no portion in the World to Come, and according to Rabbi Aba they will not resurrect, we will anyway learn from them because anyone in our generation that will do like they did and will not to Teshuva, will not have a place in the World to Come. And if they shall rise and stand for Judgment, like what Rabbi Shimon says, it will be with shame. And since it says that the main reason that the generation of the flood do not have a share in the World to Come is because they spilled their semen on the ground, as it says “Since all flesh corrupted their ways upon the earth” (Genesis 6:12), and therefore it caused that they will be blotted out from the land, above and below; so too, the same will happen to whoever does like them and does not do Teshuva.

Similarly it says in the Faithful Sheppard in the Zohar in Pinchas B: 600. And in the first part, the Faithful Shepherd said: Whoever treats lightly crumbs of bread and throws them where they should not be, and even more so one who treats lightly pieces of marrow, that are drops of seed, and throws them on the ground, it is said about them: “for all flesh had corrupted its way upon the earth” (Beresheet 6:12). Or he who throws them to a menstruating woman, or the daughter of an idolater, or a bondwoman or a prostitute, and much more so one who treats lightly the crumbs of the bread of the Torah, which are THE SECRETS THAT ARE IN the tips of the letters and the crowns of the letters, about these it is said: He that makes worldly use of the crown shall perish. 601. And how much more so whoever transmits secrets of the Torah and the secrets of the Kabbalah and the secrets of the Works of Creation or secrets of the letters of the explicit Name to people who are not worthy, who are in the control of the Evil Inclination, a harlot, about whom it is written: “For by means of a harlot a man is brought to a piece of bread” (Mishlei 6:26). And whenever bread is mentioned the meaning is the 22 letters of the Torah, and whenever ‘piece’ is mentioned the meaning is even a single Halachah.
