Sprul-pa
Sprul-pa (Tibetane: སྤྲུལ་པ , pronuntiatione tulpa; Sanscrite: निर्मित  aut potius निर्माण  'aedificare, construere') in mysticismo est notio entitatis vel rei quae solum per disciplinam generatur, cogitatio realis facta, quae sibi speciem physicam adsumpsit et idem qui cogitatum (vel ad verbum forma cogitationis, Anglice thoughtform) usitate habetur.

Buddhismus Tibetanus 
Tulpa est upaya (disciplina et doctrina spirituales), notio in Buddhismo Tibetano et Bon habita. Locutio thoughtform, tam nove quam 1927 in Tibetano Mortuorum Libro ab Gualterio Evans-Wentz converso Anglice adhibita, sic describitur: "entitatem palpabilem rei excogitatae dans, accuratissime eodem modo quo architectus solidas proprietates operum lineamentis luce impressis in tribus dimensionibus dat."<ref>Anglice "giving palpable being to a visualization, in very much the same manner as an architect gives concrete expression in three dimensions to . . . his blue-print." [http://books.google.com/books?id=rKFGit9aFssC&printsec=frontcover#PRA1-PA29,M1 The Tibetan book of the great liberation; or, The method of realizing nirvana through knowing the mind, preceded by an epitome of Padma-Sambhava’s biography and followed by Guru Phadampa Sangay’s teachings, according to English renderings by Sardar Bahädur S. W. Laden La and by the Lāmas Karma Sumdhon Paul, Lobzang Mingyur Dorje, and Kazi Dawa-Samdup, introductionibus, adnotationibus, et editione W. Y. Evans-Wentz, cum commentario psychologico Caroli G. Jung (Londinii, Novi Eboraci: Oxford University Press, 1954).</ref>

Ioannes Myrdhin Reynolds, suam vitam Garab Dorje Anglice conversam adnotans, tulpa sic definit:
Nirmita (sprul-pa) est emanatio vel manifestatio. Buddha vel alia entitas realizata multas Nirmitas tales per infinita formarum varietate eodem tempore emittere potest.
Locutio etiam in operibus Alexandrae David-Néel adhibetur, quae dixit se tulpam generavisse qui ad realem Friar Tuck monachi hilaris speciem accessit, qui deinde eius vitam propriam evolvens delendus est.

 Cogitatum 
Cogitatum (Anglice thoughtform) intra memoriam occultam Occidentalem pro notione tulpa valet; mens autem Occidentalis, a nonnullis pro interpretatione notionis Tibetanae ortum esse putatus, ad Occidentalem magiae mysticae philosophiam et usum pertinet.
