Always check credentials. I will give a small (slightly unconnected story) as an example of why its important…
Many many years ago (early 1990’s), I explored ceremonial evocation magic as that was the only books I could get my hands on locally. There were frequent points about checking and researching what you want to summon and I did this because that was the advice. However… One night just for fun I didn’t…
I was bored and had nothing better to do with the house to myself so I laid out my usual protective stuff and generally called out to any spirits nearby. I knew this was a bad idea, the area I lived in was very spiritually active and I had no idea what might be around, but I did it anyway. After a few calls to anything nearby I had no response. I was about to put an end to it when I felt a presence.
It wasn’t a great sensation tbh, and I felt this wasn’t going to go well. It circled my protection, back and forth it went. I could feel it probing. I was fearful and decided to do things properly by the rules from now. The next stage would be to ‘check credentials’, in that I would challenge it to tell me truthfully what it was, and if it had a name. It had to tell me the truth because I summoned it.
Again, it took a while for any response while it moved around, and then in my head I heard a horrible voice tell me it’s name was Azrial or something like that. It rang a very bad bell, but I couldn’t put my finger on why. By this point I was seriously in fear.
I now knew its name and then comes the rest… While trying to gather my thoughts on banishment it told me it had a gift for me. That I knew to be a bad idea to accept and rapidly prepared myself for the banishment which took quite a few goes before I could sense it had gone.
That experience left be deeply shaken and still now I can feel that fear of what a huge mistake I made. Never made it again.
Perhaps that is quite an extreme story to what you ask but it does highlight the adage: Don’t summon what you can’t put back.
If the spirit is what it claims to be then from experience it is quite understanding in any questions or checks you need. It took years for me to trust my goddess.
