Chasidut su Levitico 17:78

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.”
