The Tulku and the Nemita

The term tulpa comes from a later Western adaptation of the mind-made body or emanation body. Theosophists, the Westerners who adapted and someone say appropriated this idea, were calling these things thought forms as early as 1927. There's a Belgian French explorer named Alexandra David Neil who said that once the tulpa is endowed with enough of a fatality to be capable of playing the part of a real being, it tends to free itself from its maker's control. This happens nearly mechanically just as a child when their body is completed and able to live apart from the mother leaves the womb.
