The Torah, Deuteronomy 12:23 – 12:25: However, be strong not to eat the blood, for the blood is the soul; and you shall not eat the soul with flesh. You shall not eat it. You shall not eat it, in order that it be good for you, and for your children after you, when you do what is proper in the eyes of the Lord.
Blood is called the greatest, biggest glow, filling the desire—the Light of Hochma at its highest level. We are unable to obtain this Light until the final correction, about which “be strong not to eat the blood” was allegorically written.
Blood is the fourth part of the world, the fourth part of a desire that cannot be used because we are unable to feel adhesion with the Creator with the quality of bestowal, while at the same time feeling the enormous desires that are filled with the strongest Light. This is beyond our desires.
Thus, we have to cleanse everything from blood. That is why Kashrut laws are based on appropriate rules for animal slaughter and the extraction of blood from meat.
Question: It is written that “the blood is the soul.” What does this mean?
Answer: The soul has five degrees: Nefesh, Ruach, Neshama, Haya, and Yechida.
Blood is the lowest part (Nefesh) and that is why its use is prohibited. It is impossible to accept this fulfillment with the intention to bestow; we do not have the force to resist the heaviest egoism. This will continue until the final correction and only after that will we be able to shift to different laws.
