Hi! I'm Leander. I am very interested in Western Tulpamancy. I was told about it by someone in my meditation group and immediately started to look into it.
When I was young I would imagine daemons that were kind of like embodiments of important times, places and feelings. I wasn't superstitious or believed in supernatural forces, it was just a creative thing. It felt like it was a way to carry these with me for inspiration, even interact with them. I had many of these spirits who came and went. Nowadays its just one prevailing daemon that sticks around and seems to have absorbed several others. S/he would be the basis for creating a Tulpa for three main reasons:-
S/he wants that to happen. like, a lot!
I think s/he would be a perpetually good influence to have around.
S/he's too wild to "integrate" into my personality without becoming awkwardly eccentric.
Currently I actively practice meditation and psychonautics. I don't know how much they will help with the process of Tulpa creation but I suspect they won't hinder it.
In my past I've been involved in many esoteric/occult circles. Again, I'm not superstitious or believe in supernatural forces. My framework for such things was based in the power of the human imagination, creativity and meaning.
