Tulpa is a spiritual discipline and teachings concept in Tibetan Buddhism

Tulpa is a spiritual discipline and teachings concept in Tibetan Buddhism and Bon. The term “thoughtform” is used as early as 1927 in Evans-Wentz' translation of the Tibetan Book of the Dead. John Myrdhin Reynolds in a note to his English translation of the life story of Garab Dorje defines a tulpa as “an emanation or a manifestation.” The 14th Dalai Lama is said to be partly a tulpa of Chenrezig, the Bodhisattva of Compassion. The Dalai Lama mentioned in a public statement that his successor might appear via tulpa while the current Dalai Lama is still alive.

As the Tibetan use of the tulpa concept is described in the book Magical Use of Thoughtforms, the student was expected to come to the understanding that the tulpa was just a hallucination. While they were told that the tulpa was a genuine deity, "The pupil who accepted this was deemed a failure – and set off to spend the rest of his life in an uncomfortable hallucination."
