Tibetan mystics have long practiced a method to create sentient beings from the power of concentrated thought. Explorer Alexandra David-Neel was the first Westerner to discover the practice. “Besides having had few opportunities of seeing [tulpas], my habitual incredulity led me to make experiments for myself,” she wrote in her 1929 book Magic and Mystery in Tibet. “My efforts were attended with some success.”
Tulpas remained the preserve of occultists until 2009, when the subject appeared on the discussion boards of 4chan. A few anonymous members started to experiment with creating tulpas. Things snowballed in 2012 when adult fans of My Little Pony: Friendship is Magic – known as “bronies” to anyone who’s been near a computer for the past three years – caught on. They created a new forum on Reddit and crafted tulpas based on their favourite characters from the show.
