I've been an occult practitioner for many years now, and I can tell you that Tulpas tend to be a bad idea.
At the end of the day, they share a mind with you, and they tend to be intelligent enough to know you can unmake them just as you've made them. If you fuck up (and you will, eventually, because they know what makes you relax your guard because you share a mind) they will take over.
Keep in mind the practice comes from Buddhist monasteries, where the people practicing it are constantly surrounded by a multitude of people that are watching out for strange behavior and can help in a pinch.
>Can you really make a sentient being inside of your mind?
Certainly. After all, everything your senses recognize is created inside your mind.
