I think normally spirits etc are not bothered with human existence.. But when you do OBE training and all that Occult stuff, you are raising your prana or energy or whatever you want to call it and it is like a beacon in the dark to them. Suddenly you are visible to all these characters and they are out to get a piece of that prana or energy etc. Also mental dedication is a great part. The mind is powerful. Dedicate something to a spirit and they can receive it. Otherwise they cannot. They are very possessive, but it needs to be dedicated and you need to be strong enough to be visible to them. I do not recommend this. I am just describing how most people in the occult get problems.
I am not in the occult, nor did I seek out Azrael. Azrael came to me. I am only a Jew.
I have no "prana" I don't understand what that is, I have no special powers or abilities, and I am not more spiritual than others. I don't know why I keep seeing this angel since my childhood, but I do know it is helpful. My best guess is it isn't anything special I did or earned, but a gift from god to comfort me and possibly save me from myself
