Bestial Sorcery

Lilith is also known as the 'screetch-owl.' When she was excommunicated, she was outcast to the desert with the hyeanas and serpents.
Sammael is the serpent in the Garden of Eden.
Leviathan is the Oceanic Dragon with Seven Heads.
Behemoth is a bipedal elephant.
In folklore the magical lodestone comes from the belly of the frog who is Satan in disguise. The black cat, the bat, and the wolf are all relegated to the vampire, who is also known as the Son of the Devil.
Beasts and monsters have been allies to the Devil and Witch since time immemorial. Echidna ('she-viper') is considered the mother of monsters in Greek Mythology, and is the wife of Typhon ('hurricane'), an avian-serpent like giant.
Hekate has many forms, mostly bestial. She is know as Leader of the Dogs (Skylakagetis), serpents (Opheôplokamos ‘Coiled with Snakes’, ‘With Snaky Curls’), but is also known for appearing as a bull-formed (Tauromorphos), cow-eyed (Boopîs), and 'she-wolf' (Mormolykeia).
In Japanese mythology there is the goblin demon king Sōjōbō, the red faced goblin with raven wings. Under Sōjōbō are the kerasu, the humanoid crow mountain warriors. There is the nodeppo, the flying squirrel vampire, the bakenekko, two tailed cat, the white demon cat who taught swordsman philosophy, magic, and of course, swordsmanship. The most famous is the nine tailed fox kitsune, a shapeshfting witch. Even more, there is the kappa, the hollow headed turtle demon found among small bodies of water.
Japan, as you can see, has a rich history of bestial demonic creatures. Some are merely mischevious (bakenekko), some are extremely brutal (nodeppo and kappa), while some are more grey (tengu).
Bestial Ritual
Ritual is a great way to acheive bestial mindset and structure. My prefered way is to make a little fire and pour some fresh herbs into it to make a blazing fire with unique smells in a private outdoor area. If privacy permits, strip down to nothing to really get into the shape of the beast. Mimic its sounds and movements to the best of your ability.
Since my current living situation makes it near impossible to really engage in bestial psychodrama as mentioned above I use my martial arts as a way to mimic animals. The style I was taught utilizes eight different animals, so taking that knowledge I can adapt those animal shapes into whatever animal I choose.
I also have certain workouts dedicated to certain animals concepts, or I manipulate basic calisthenic movements to make them fit into the animalistic form. Such as air squats with a jump I call Bullfrog Squats, there is already a pushup varation from Judo called a Scorpion Pushup, and a WeckMethod Squat I call the Phoenix.
Play and enjoy. Bestial magic is less about results in love or career and more about opening your consciousness to its instinctual nature. As a Satanist/Chaos Magician, it is best to learn to play in the magical arena then be bogged down by illumination so much. Illumination has its place, but especially for the younger people out there, magic is about suspenaion of disbelief to achieve a sense of freedom. Bestial Sorcery is an excellent method.
