Great discussion .. I would say the offering of blood and the offering of life are two distinct but related operations....some things cost ..some beings only pay attention to your requests when your buying drinks as it were...the incarnated energy released at death is significantly more potent than the prana or chi released when blood is drawn....I believe that blood and or life can be a good offering...but don't commonly give blood during rituals...if I shed any during consecration and carving of ritual items I say that blood to ...who ever I'm asking to empower the item...if I draw blood or take life ill offer it to someone...like the kings of old did...i.e. all these men I give to you Odin...a common thing at one time...and I wonder if it isn't being done today on a grand scale at times....the death of a living being released it's energy in masse...much more than a cup of blood...was triblinka a ritual for the greater apotheosis of hitler? Was sorcery so easy on whaleing ships that it became accidental..should I seek a job at a slaughter house? How many of the " senseless" ward today and in antiquity were means to offer massive amounts of life force...
These questions occur to me, and more than that, realization that it is an addiction...even for civilizations....we as a civilization are addicted to the blood of the earth...oil....and the mexicas or Aztecs were addicted to the blood of there enimies offered at the templo mayor...and successfully built an empire on that energy...just like we have from oil....
Are offerings of abnegation and mortification related...it's all energy so to some degree of course...but while fasting and killing can both aid your aims ...they feel different...and no civilization has been built on fasting ....
The subject of blood offerings and death offerings opens up not a rabbit hole...but a black hole...
This is excellent addition to the discussion. Taking civilizations as subjects offering life to thrive is something I didn't think about before, but it damn makes sense.
On that note I must say that we do not work on oil only, but on blood too. Our civilization constantly needs some war to be going on. Conflicts in Africa, Ukraine, Tai-Wan, border of USA and Mexico, We are civilization of war and sacrifice indeed. The Bible being the core book of civilization is indeed testament and proof of it.... also a core source of that program, possibly. Among other things, war greatly speeds up technological development, that is of great importance in the tactics and can decide the winner of the war.
Oil is of course also an aspect, blood of Earth, excellent description and excellent observation. Makes me think about limits of our resources, not only in physical sense, but also in spiritual one. There is only as much blood out there we can shed for society to run. And we can run dry.
Don't know about black hole, but addiction is definitely a thing here. The never-ending need to increase dose because current one no longer suffices... thanks to dulled senses or whatever is the reason. Lack of balance on global scale.
