244. "The one lamb (Heb. keves) you shall offer in the morning, and the other lamb you shall offer towards evening" (Shemot 29:39 and Bemidbar 28:4). And about the hidden matters (Heb. kivshi) of the Merciful One, the sages have taught: 'Why do you probe into the secrets of the Merciful One?,' THE MEANING OF WHICH is: Matters that are of the mysteries of the world, let them be concealed under your dress. Just as clothes cover the body, so also must the secrets of the Torah be kept covered up, and this applies even more to the secret of the sacrifices, which are like a wife drawing near to her husband, WHICH IS WHY A SACRIFICE IS CALLED 'KORBAN,' FROM THE SAME ROOT AS THE WORD KIRVAH, MEANING NEARNESS.

245. And just as the proximity of the two of them, OF HUSBAND AND WIFE, has to be in concealment, so also must the sacrifice be concealed from the wicked, the impudent, the immoral and practicioners of incest, who have no shame and no modesty. And there are bastards of a number of sorts, children of incest, of those who have intercourse during menstruation (Heb. nidah). NIDAH MEANS THAT Hei, WHICH IS THE SHECHINAH WHO IS CALLED 'HEI,' has moved (Heb. nad) away from her, and in her place is a bondwoman, daughter of a strange El, a prostitute. And this is a secret of: "For three things the earth is disquieted...for a slave when he becomes king; and a fool when he is filled with food...and a handmaid that is heir to her mistress" (Mishlei 30:21-23). For the Hei has moved away from its place, which is the Queen and is the Good Inclination, and in her stead has come in a handmaid, the Evil Inclination.

246. And the secret of the matter is to be found in the verse: "It seems to me there is as it were a plague in the house" (Vayikra 14:35), namely, the impure blood of menstruation. Just as in the one case, OF THE PLAGUE, "then the priest shall shut him up for seven days" (Vayikra 13:21), so also in the other: "she shall be seven days in her menstrual impurity" (Vayikra 15:19). Happy are the organs that are sanctified at the time of intercourse, for they are called 'the wood of the burnt offering,' for they are engulfed by holy fires from the Name Yud Hei Vav Hei, WHICH IS ZEIR ANPIN, who takes hold of their fire. And for this reason IT IS WRITTEN: "Wherefore glorify Hashem in the regions of light" (Yeshayah 24:15). Thus the mysteries (Aramaic kevesh) of the Merciful One are: "The one lamb (Heb. keves) you shall offer in the morning, and the other lamb you shall offer towards evening."

247. And the end of the verse continues: "and a tenth part of an efah of fine flour" (Bemidbar 28:5). That is, happy is he who draws down from his brain a drop of clean refined flour without impurity and waste, AT THE TIME OF THE MATING, and this is hinted at in the letter Yud of Adonai, AND THAT IS WHY IT SAYS 'A TENTH PART' that includes the ten Sfirot. And she is to be "mingled with a fourth part of a hin of beaten oil" (Ibid.). That is, it is mingled from FOUR, NAMELY, Scripture, Mishnah, Talmud, and Kabbalah, ON WHICH THE RIGHTEOUS BEAT THEMSELVES AND SO RAISE UP THE FEMALE WATERS FOR ITS UNION.
