Tetrahedron
The tetrahedron is not a satanic shape. It has no intention, it is neutral. Like all sacred geometry it simply IS.
It becomes bad when used to rip the aura, it becomes good when used to destroy e.g. snake venom or cancer cells.
This is how we Curanderos (spiritual healers) use it emanating etherically :
Most Powerful Killer on the Planet. This is the demolition shape. It tears down, destroys, eliminates, rips, annihilates [exterminator, wipes out, eradicator, annihilator, dissipater, break up, break down, cut up, chainsaws, tear, shatter, expel, eradicate]. Breaks down the disease or condition in the body. Its weight is distributed so that it moves end-over-end, tearing holes, ripping etheric, ectoplasmic, and subtle energies apart; preventing a quantum or endomorphic field from existing. Tetrahedra are found in many shapes. It causes destructiveness to clear a path for the plan, whatever the plan is. It is the ultimate killer.
This shape is a Platonic solid - it provides a limited and sharp perspective.
The purpose of the tetrahedron is to clear the path for the plan (example, if you want to be smarter or become a writer, you need to break down patterns first). Sacred geometries stay in their shape until a higher geometric shape encounters them. To remove tetrahedra you need higher shapes to break them down and absorb them.
Do not let tetrahedra flow through the air because people would breathe them; do not leave tetrahedra in water people or animals drink.
There are approximately 400,000 blue tetrahedra in the auric field and physical body of a depressed person. If you have 900,000 blue tetrahedra you will be so depressed you can't get out of bed. The tetrahedra tear through the emotional body and the ectomorphic, endomorphic, and quantum fields. When these fields are gone, things cannot hold together. Depression is a state of consciousness that supports the ripping and tearing of self-esteem.
Blue - Lack of self-esteem (depressive, helpless, 'giving up quality') builds blue tetrahedron.
Red - There are 4-5 million red tetrahedra in a person with the AIDS virus, breaks down the field to make space for the disease. Lack of self-respect (take action in directions that feed our not getting respected) builds red tetrahedra in the physical body and material plane, the lymph system can't work. Use several million red tetrahedra to break down a quantum field (e.g., pollution in a pond that is not a water source).
Medium blue - chemical depression.
Dark blue - hormonal depression
Black - When someone has leprosy, black tetrahedra tear through the physical plane - that is, through the flesh and organs.
Black - karma builds them. If you see black cones or black tetrahedra coming out of the temples of someone's head, you are seeing someone who kills people. If you see it out of their armpits, you are seeing someone who steals.
Yellow - asbestos has lots of.
