So I decided that creating a Tulpa would be a good idea, so I looked up a lot of data on the internet. After learning a lot, I started imagening an orb floating beside me at all times, which I told stories, and about myself and my family. I left the personality, gender and form for itself to decide. (Hence the placeholder orb.)

In the evening I suddenly realized that I had been referring to it in my mind as "her" and "she", whilst I had decided that the Tulpa could decide the gender later. I took this as a subtle hint from Tulpa-san (I haven't got a name yet.), so from that moment she was female. At least I know one thing about her know.
I told her more stories until I couldn't stay awake anymore.
