I’ve written a blog post some time ago that doesn’t directly refer to Tulpas, but does somewhat answer this question of the social desires that I fulfill through this method. I think this sufficiently answers your question, although if you feel like it doesn’t, let me know, and I’ll write something for Tulpas directly.
What types of social desires do you satisfy through your tulpa which you have not been able to with your online or meatspace friends?
