Hello all, I have recently been reading and learning a little about the Djinn, and have come across a very convincing spell to summon them, here is my concern, I have never worked with them personally nor do I know anyone that has. I can't find enough information about them online to make myself comfortable enough to work with them just yet so I guess what I am asking is, what do you guys know / suggest about them? Any information and guidance will be much appreciated, thank you
