Using outside entities to astral project Options

I was looking up the goetia on the website for this forum, which is odd because I'm not at all fond of the results I've received while using it, and I see that it says that there are some spirits who aid in astral projection. Now, while I don't think I would ever use any goetic beings for something like that, it made me wonder more about the idea of using outside entities for the purpose of learning to astral project and the more I think about this the more interested I become.

Has anyone here used an outside entity before to help them (even in the smallest of ways) to astral project?

I'm not exactly asking to have a demon pop me out because it would certainly be odd in the long run to have to call up a demon to leave my body, maybe just put the necessary smarts in my head and act as a teacher so that I wouldn't have to struggle with buying books that turn out to be more like "So-and-so's Very Personal Adventures in the Magical Secret Wonderland Place That You Still Can't Get Into".

Well, I've got nothing better today since the family's home for some silly holiday or another. I'm going to see if I can't transvoke Baphomet, who's been helpful to me in the past and who I'm starting to think might be God, and see if they won't help me out again.
