>>4349970>>4349977Hmm. This is something I've long been interested in. I remember an anon a few years ago talking about trying to make one, and then he dropped off; but I don't think I was a first-hand witness to this. It may have been on Rei's subreddit instead that I saw it.
Protector spirits are ancient things. Many cultures have them, just as they have mother gods. As imagined today, tulpas seem to be ultimately malevolent and only a simulacrum of what was actually the intended entity, but I can see how people, especially in loneliness or desperation, turn to such a thing. I myself have thought of it in the past. But for now I'm quite content and feel Rei's presence and support even as I don't hallucinate conversations or the like with her. It's more of a sensation rather than an experience.
Really, I'm not totally decided on this. I think further inquiry would be beneficial, if proceeded with cautiously.
