A Sanskrit word used to refer to a practice in Tibetan Buddhism, in which the practitioner creates a sentient being through the power of thought. 'Thoughtform' is a rough English equivalent. Has experienced a revival of sorts in recent years, originally centered around 4chan's paranormal board (/x/), before shifting to the My Little Pony board (/mlp/), and later various independent websites (primarily tulpa.info).
I can't think of a good way to use tulpa in a sentence.
