Of all people to ask about corruption through filth, people came to me. I guess people have no clue as to how immature my potty humor is and how funny I find this subject. So I will try to remain as straight laced as I possibly can. So lets start at the basics of this. Per Zoroastrian understanding, anything leaving the body is Ahrimani or evil. This goes from your exhale of breath to potty behavior.
The Zoroastrian’s take this so seriously that their priests use a veil to keep the exhale from corrupting the fire that is to always to be burning in their temple. This comes from old Hindu practice of never allowing the heat to die. This took devotion away from the God/s. Primitive Hindu understanding was originally internal heat before the concept of pranja was introduced. All ceremonies, be it just throwing Soma in the fire for celebration or animal sacrifice which included cooking and eating the animal, the fire or heat was the way to offer to the god/s. The hymns that were sung around the fire was the offering of devotional energy which sustained the god/s immortality. So, enough about the ritual fire.
The 2 worst types of filth are feces and menstrual blood. Menstrual blood should be obvious due to Ahriman’s corrupting kiss upon Jeh. Now feces on the other hand had the ability to corrupt so powerfully that the Zoroastrians had specific toilet behavior that involved sealing it in jars, saying a prayer over it that dedicated that to Ahriman, then burying said pot. One of the major reasons why feces is a major corrupting conduit is that it attracts druj to prosper and multiply, i.e. flies, and maggots and such. Anything that has the ability to attract physical druj is that much more powerful to attract spiritual druj. Nasu which is the druj that is most assosiated with death has been correlated to the image of a large fly.
Anything that is to be highly stinky such as rotting flesh, feces, urine, and such emits gasses that can also corrupt the fire. Anything that can corrupt the fire can corrupt you spiritually. Urine is also considered Ahrimani since it too is odorous and will attract druj. This also includes any dead matter such as dead skin, fingernails, or hair. The Zoroastrians would take all hair clippings, dead skin, and fingernails and bury them in a jar with a prayer so that the druj could not make spiritual weapons.
Sexual fluids such as semen and menstrual blood are also highly charged with negative spiritual energy. The purpose of mixing semen with any other corrupted matter and allowing it to charge for 3 days and 3 nights and thus to be used on the 4th day or night correlates with the Zoroastrian understanding that the first 3 days the spirit has left the body in confusion. On the 4th day is when the spirit is presented with the Bridge of Consequence. Now take into effect that the sperm cell in semen lasts up to 72 hrs, thus negating the life potential of the semen in making it a corrupting fluid. The same goes for the discharging of menstrual blood since it is originally the discharging of the blood within the uterus to begin the process of life if the egg is fertilized. Obviously if menstruation has occurred then the beginning of a new life cannot occur and therefore that is why it is also referred to as dead blood.
So with all this being said it should be self evident as to why these particular materials are used in demonology. Any of these materials can corrupt and are considered filthy, both physically and spiritually. So for example, should you wish to blaspheme any particular RHP religion the easiest way to desecrate it would be to use any of these corrupting materials upon anything the RHP religion would hold sacred because it would attract large numbers of demons to attack said object that was corrupted. To make this more easily understood it would be like taking the original pages of the original Bible and wiping your ass with it.
To heighten effects and multiply the charge of said material, combining any assortment of this with dirt and made into mud will highly charge what you are trying to accomplish spiritually. So to put a combination of these things upon your body will corrupt you both physically and spiritually and make you a beacon to demons. And should you choose to participate in masturbatory behavior you will also be charging the demons that you are surrounding yourself with. Whatever thought forms you are using and emotion that you are sending to the attending demons is how you communicate your request to them. One cautionary note, it is highly recommended not to ingest any of said mixture, unless it is semen that has not reached its expiration of 72 hrs.
Though talking about and playing with these corrupted materials can be somewhat entertaining or disgusting, do realize that all this still brings about life and creation by fertilizing soil and your exhaling is what plants use as part of their growth process. Then we turn back around and grow said plants in the soil that is corrupted by the dead materials that we either eat or will feed the animals that we end up eating. Which is another example of creation through destruction. Also the performance of any type of sexual act that does not create life is considered corruptive to include fallen seed, emitting seed in the anus, or orally. And any type of pleasure that takes away from the focus and devotion of the RHP godhead is considered to be corruption through sin, allow your own morality to guide you into the depths of your own depravity.
So in closing should you choose to use corruption through filth be careful of health issues that can occur through this type of behavior, maintain cleanliness before and after said acts, and should you wish to bring about a spiritual attack on someone or something, this is how you would attract demons to said target. This about the driest and nonchalant way I can approach this topic in all seriousness. And may you find success in your own workings with said material.
