In theory you could.
Best advice I’d say would be respectful by being mindful and in tune. “What to be careful for” sounds like a lack of trust. I think a lack of trust in what the Gods/Goddesses have to show and offer can be disrespectful. If you ask for something, be open to everything they may have to show you. They really makes time for all their people though, and it is never half-assed. Show them the same when they come around.
Good advice, I really like that answer.
To "know the procedure" and "doing things right" is not nearly enough in my opinion during any summoning. Before all the props, the prayers to the Gods, the sigils drawn and everything else, one has to absolutely understand that working with a God of Hell means before anything else to completely trust them. If one starts a summoning wondering, confused, doubtful and so on, the Demon will feel this and won't likely waste His/Her time responding to someone who's not even sure he/she wants to work with them. Chances are the person will manage to miss the answer anyway.
This year I found it particularly helpful to start off by always asking myself if I really trust a Demon as much as I think. NOT because I don't trust Demons or Father Satan of course, but because I normally don't trust anyone unless I've have a long enough relationship with.. so trusting someone out of the blue is not something I'm used to to, therefore it comes to me as difficult.
With Demons and Satan this problem doesn't seem to exist at all. Somehow, I can easily show a Demon my trust and somehow I feel they know I trust them, whether they respond in an obvious way or a very subtle one I may easily miss. But it FEELS like something.
I think it's a bit like knowing you're in love. You're the only one that can know it. If you feel something, a change in yourself, and feel more confident, readier, somehow stronger or better, chances are the Demon hears your thoughts and makes sure you don't give up on that trust.
In short, a Demon is the best parent/friend a human could have. So, always trust Demons completely. If you're unsure whether or not an entity you may feel around is a Demon just go through Satan or your Guardian Demon or a Demon you know well enough and ask them.. with all the fucking greys these days I'm sure some people are finding it harder than normal sometimes to tell who's who when it comes to new contacts.
HAIL SATAN!!!!
