Tibetan mystics have long practiced a method to create sentient beings from the power of concentrated thought.

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.
