According to Spells of Magic, one of the most direct ways of shape-shifting is to choose an animal and begin to understand the creature. The next step is to merge with the animal in spirit and shape-shift in the Astral Plane. Once the shape-shifter has become acclimated to transforming in the Astral Plane, making the transition into physical shape-shifting is much easier.
Another spell from Spells of Magic is for people who wish to become an animal-human hybrid. The spell begins with the following chant: "Gods of nature and divine I want to be part animal. Please grant me my wish and I will honor you with all my heart. Grant me my wish, make me a (say animal you wish to become).'' The spell should only be chanted one time. If done correctly, the spell can take anywhere between 5 minutes and one week, but it may also take longer, depending on the chosen animal. There is another spell from Alizon's Psychic Secrets called the Blackbird Spell. The first step is to take a picture of a bird, or take a bird feather, and place it in front of a Chi Generator. Placing a strand of hair or saliva next to the feather or picture will merge the spell caster and the animal. The next step is to cast a circle of light. Imagining the bird as large as a person will draw the spell caster closer to a bird-like essence. It is important to breathe the aura of the bird, and the user will begin to notice a physical transformation. This spell can be tailored to any animal other than birds, including mythical animals like unicorns, dragons and centaurs.
