Tulpas have been a very big field of study to psychic sorcerers but i feel tulpas are misunderstood as a whole. First off tulpas are at best a projected part of the practitioners sub-concious and at worst a self induce illusion like drug bugs are formed from paranoia, or feeling something you see in a daydream.
Tulpas are “made” without any real substance or magick for example some dumbass could jump off a building thinking he has wings he can see his wings he can feel his wings but he cant touch or use his wings cause their not real so he falls to the ground and dies cause he was dilusional.
Tulpas in this regard are the same they are only thoughtforms within your own mind we as spiritual beings are real cause we are made of energy we are external from source for a being to exist energy must be manipulated in multiple ways with the being and its features already preconcieved by the ideas and thoughts of the creator.
The being also needs a vibrational frequency which tulpas do not have, it must also be capable of individual thought which tulpas cannot do because their “thoughts” are programmed.
Tulpas are not real because they are not made with substance neccessary for life. Yog-Sothoth exists because he created himself with dark matter from the abyss which was before creation,ra exists because he formed himself from energy from the sun.
In conclusion my point is learn to creaate demons and angels instead of self induced illusions.
