Tulpa is a concept in Theosophy, mysticism, and the paranormal, of an object or being that is created through spiritual or mental powers. Modern practitioners, who call themselves "tulpamancers", use the term to refer to a type of willed imaginary friend which practitioners consider to be sentient and relatively independent. Theosophy and thoughtforms 20th-century Theosophists adapted the Vajrayana concept of the emanation body into the concepts of 'tulpa' and 'thoughtform'. The Theosophist Annie Besant, in the 1905 book Thought-Forms, divides them into three classes: forms in the shape of the person who creates them, forms that resemble objects or people and may become ensouled by nature spirits or by the dead, and forms that represent inherent qualities from the astral or mental planes, such as emotions. The term 'thoughtform' is also used in Evans-Wentz's 1927 translation of the Tibetan Book of the Dead. The concept is also used in the Western practice of magic. Occultist William Walker Atkinson in his book The Human Aura described thoughtforms as simple ethereal objects emanating from the auras surrounding people, generating from their thoughts and feelings. He further elaborated in Clairvoyance and Occult Powers how experienced practitioners of the occult can produce thoughtforms from their auras that serve as astral projections which may or may not look like the person who is projecting them, or as illusions that can only be seen by those with "awakened astral senses". Alexandra David-Néel Spiritualist Alexandra David-Néel stated that she had observed these mystical practices in 20th-century Tibet. She described tulpas as "magic formations generated by a powerful concentration of thought." David-Néel believed that a tulpa could develop a mind of its own: "Once the tulpa is endowed with enough vitality to be capable of playing the part of a real being, it tends to free itself from its maker's control. According to David-Néel, this happens nearly mechanically, just as the child, when her body is completed and able to live apart, leaves its mother's womb." She said she had created such a tulpa in the image of a jolly Friar Tuck-like monk, which later developed a life of its own and had to be destroyed. David-Néel raised the possibility that her experience was illusory: "I may have created my own hallucination", though she said others could see the thoughtforms that she created.
