The systems you use to summon various entities are built up as they are for a reason and that is to attract that particular kind of spirit. Whatever system you use has been tried and tested. That is not to say you cannot build your own or modify them once you no longer need the words and tools.
I have no idea what level you are at, but I would lay your foundations with the well tried and tested and in doing this, you will learn what things feel like, you will sense things and learn correspondences. Having written up your experiences in your journal, you will be able to compare notes.
Of course, you don't need to follow the rules at all, you could just do 'what works', but I think you will have many disappointments whilst you are finding out, having said this, they pretty much follow a pattern and as long as you can banish what you summon, then enjoy and learn.
Some magickians can just stare at a sigil and bring forth an entity, so I am not discounting easier methods at all.
Anyway, don't be discouraged, the longer methods are just while you learn, they are not forever (IMG:
