Chasidut su Levitico 11:78

The soul is the nefesh Elokis, “the Godly soul,” since it is a piece that was hewed off of the Divine. The nefesh ha-bahamis is concentrated in the blood, which is why loss of much blood causes death to the body. The Torah severely prohibits¹⁰⁵Ingesting blood carries the punishment of kares; the soul is disconnected from the Divine, and the individual dies at an early age. ingestion of animal blood because what you eat influences your character.¹⁰⁶See further Nachmanides’ commentary to Lev. 11:1 3; Mesillas Yesharim, Chapter 11; Sha’ar Ha-Kedushah, 1:2, Degel Machaneh Ephraim, Parashas Eikev s. v. u-maltem. Since the blood contains an intense form of the animal’s vitality and nature, eating it would cause the human nefesh ha-bahamis to become too strong.¹⁰⁷See further Or Ha-Chaim on Lev. 17:10. The organ with the most blood in the body is the liver. The nefesh ha-bahamis is therefore said to be located in the liver, or the left half of the heart, a section of the heart that has excessive amounts of blood. The home of the nefesh Elokis is the mind, and it is concentrated in the right half of the brain. The nefesh ha- bahamis is sometimes called yetzer hara, “evil inclination,” for it draws the person to evil, the selfish behaviors of the animal world. The nefesh Elokis pulls man to attachment with the Divine and is called yetzer tov, “the inclination for good.”

‎Genesis 25,22. she said: “if so (that the children already quarrel ‎within my womb) ,what is the purpose of my existence?” We ‎can understand this complaint of Rivkah on the basis of a ‎comment by the Ari’zal that righteous women are spared ‎the pain and discomfort of pregnancy. Rivkah, while experiencing ‎even more than the normal amount of pain and discomfort ‎during her pregnancy, had concluded that this was proof that G’d ‎had not considered her righteous. Moreover, it is a tenet of our ‎faith that if someone is not a “good” person, such a person will ‎not serve as a receptacle for anything holy or potentially holy. ‎Our sages have based this insight on Leviticus 11,15 ‎את כל עורב ‏למינו‎, “and every subspecies of raven each according to its ‎species” (is forbidden to eat). [The word ‎כל‎ in that verse means ‎that even close association with something ritually unclean, i.e. a ‎raven, is an obstacle to such a person hosting holy spirit, etc. Ed.]‎ According to Bereshit Rabbah 63,6 whenever Rivkah ‎passed a Torah academy Yaakov would make an effort to leave her ‎womb, whereas when she passed a pagan temple Esau would try ‎to leave her womb. Thereupon she went to ask G’d about this ‎strange phenomenon. The Midrash states further that the ‎word ‎זה‎ in our verse refers to the fact that originally, -if not for ‎her complaint- Rivkah was slated to become the mother of all the ‎twelve tribes; seeing that she appeared to find fault with G’d’s ‎arrangement, she was told that she would become the mother of ‎only two sons, one of whom would be Esau. One of the sages in ‎the Midrash takes issue with the literal meaning of Yaakov ‎and Esau respectively having shown awareness of when their ‎mother passed a Torah academy or a pagan temple, and states ‎that, of course, this is merely a simile, and that Rivkah consulted ‎with the heads of the academy founded by Shem and ‎subsequently headed by his great grandson Ever. According to ‎another opinion offered, Rivkah knew that the source of holiness ‎is the One known as ‎אנכי‎, and when she exclaimed ‎למה זה אנכי‎, she ‎expressed her confusion how she could be the receptacle of a son ‎who clearly strived for holiness if she was not worthy. On the ‎other hand, if she were worthy, why did she experience such a ‎difficult pregnancy? G’d put her mind at rest, telling her that her ‎difficulties did not mean that she was not worthy, but that the ‎other son who would be unworthy was the one that caused her ‎present problems.‎

It was said of the Baal Shem Tov that he learned all the names for all the remedies in each of the seventy languages from the Biblical section enumerating the twenty-four impure birds (Leviticus 11:13-21). I seem to remember that the Rebbe also said this of the Baal Shem Tov.
