Transvection is the supernatural act of levitating, floating or more specifically flying through the air. While levitation and magical flight can equate to acts of stage magic or astral projection through the use of psychoactive entheogens, transvection usually refers to the experience of bodily movement in defiance of gravitational laws.
Witches in medieval Europe were frequently depicted flying up chimneys and in the air by means of broomsticks, various wild animals, or even during acts of sexual intercourse; however the consensus of modern Neo-Pagans is that these images remotely alluded to the practice of entheogen use, either for folk shamanic purposes surviving from the stone age, or perhaps even as a form of recreational drug use.
There is some pre-Christian evidence of transvection in Norse Shamanism that correlates with reports of flying and levitation in many early shamanic and mystical traditions around the globe.
Flying saints and Hindu and Buddhist mystical practitioners known as Siddhis and Iddhis are known for acts of spontaneous levitation, reported during times of intense or particular religious or meditative devotion. Though this is not to be confused with Indian street performers, famous for climbing ropes that go nowhere and other kinds of stage magic adapted to street performance.
