Blood in Magic
Blood is binding in magic. More-so than most other things. I am going to break down my understanding of basic blood magic in this post.
Blood in History (a very short, incomplete summary)
Through parts of history, blood was understood to be the life-force of a person. During belief of the four humors, it was said that those with blood as their predominant humor were in most health; with good constitutions; and maintained levelheadedness. This was true so long as the blood was not entirely out of balance. Once removed from the body, it dries up and turns brown, becoming dead. Even in "death," blood would be seen as valuable in medicine. There was value seen in the continuation of "good" blood, seen in the importance of bloodlines. Royals were said to have different blood than the layman. Gods were/are said to not bleed at all, as losing blood would be losing life-force, and they are believed immortal. There are even ritualistic blood substitutes that prevail today in use of modern religion.
Personal Take on Blood in Magic
Blood magic is binding magic. If one chooses to believe in blood as life-force for spiritual, religious, or historic practice reasons, then it holds ground for those reasons. Outside of those, I maintain it would continue to be binding as per magical theory. To explain this part of magical theory, blood is a genetic tag-lock. I am going to give my personal correspondences and belief systems around blood work so that it may be more easily understood by some.
Red: vitality, connection to the roots of life, activity, warmth/heat, power
Blood comes from the body red, and once removed for a long enough period, turns brown. It begins fluid and turns into something which crumbles like ash. If enough is lost, the living physical entity is considered dead themselves. With loss of blood comes a loss of vitality and activity, all warmth is lost from the body, and the connection to the roots of life are severed.
Iron: strength, protection, power, courage, conquest, mortality, binding force
Blood has a metallic taste which itself could be used as correspondence, but this taste comes form the iron used to create hemoglobin necessary for red blood cells to carry oxygen throughout the body. Without oxygen being delivered throughout, the body would not function. Iron is in celestial bodies, such as stars. It can be associated not only with the Earth, but with the universe as well. This well mirrors the physical body, and the spirit. (Stars that begin forming iron in their core are also on their way out, further associating with mortality with the material, aside form its association with blood.) Iron is fantastic in binding magic as it is commonly known as a strong, ungiving thing. (Not to mention its wide use historically and modernly in binding items such as shackles, chains, and cages.)
By using blood in magic, you are taking something which is vital for life, and integrating it into your work. Once it is used, the energy cannot be separated from the working, as you have given life energy to it that now belongs to the work. If used in fluid form, and it is your blood which is given, the energy is still tethered to you. Anything that contains your DNA is going to be a genetic tag-lock. This binds the working to yourself and your life-force, making the working inherently binding (a genetic tag-lock) on top of any conscious binding done in the working as well. If the blood is "dead" before the working, it becomes tethered to earthen energies of the area, and binds itself accordingly, unless consciously bound elsewhere, such as a designated object or entity. I specify conscious binding, but energies of blood may also bind itself elsewhere due to unconscious effort from an entity by means of emotional influence. Dead blood still contains DNA and has potential to be a genetic tag-lock. If this is not desired, I recommend setting the dead blood in the sun or in high heat for a few hours. This will break down the cells and allow it to be solely a component.
Because blood magic deals with life-force, it is considered very powerful and does take more to dismantle if the initial working was done properly. For the same reasons, I recommend practitioners are mindful when using this method in spell-craft, as unconscious binding may occur due to lazy, inattentive, or inexperienced energy practices. After the working has been completed, the effort it takes to undo a blood spell if you have a change of heart is very difficult and something to keep in mind before undertaking blood magic.
I will make more posts in the future that talk about the topic of blood in spell-craft, as I find the implementation and specifics fascinating. One such post will be a brief touch upon blood in protective magic, which I am excited for.
