If I was just starting out approaching the daimons through Verum, and the practice of Goetia in general, I hope someone would tell me the daimons firstly appreciate sincerity. Come as you are, and engage honestly as you would with anything you feel is important to you.
When approaching them it helps to know you are on a mythic journey. Some of the ritual framework make no sense from a rationalistic left-hemispheric perspective , but take on whole new importance when you think of the rituals l as protocols of inter dimensional diplomacy that get their attention, and then create a space for them to meet us. The mythic space is made of stories -and the world is a mythic space.
FYI, for deep discussion of this point, that we are in, and are always in , parts of The Imaginal, see Patrick Harpur’s excellent book ‘The Secret Tradition of the Soul, (2011). I stumbled upon this fact of our existence myself, but I am an artist, so we all eventually get there.
I know some approach the daimons through more Abrahamic mythic framework, and others through more Greco-Egyptian mythic framework, but both can work just fine.
The daimons tend to mold themselves according to our expectations , our mythic framework and our character. So having good character is very worthwhile here. Jake said hanging good character is like having a super power. Part of having good charter is keeping your word.
To that end, I would strongly caution be absolutely sure to hold up your end of any pacts you enter into, and keep your promises to them, even if you don’t totally believe in them, like I didn’t when starting out. They are not demons from Hell - but they are liminal beings and not all together safe. I will eventually relate a personal story from one of my early fumbling attempts at Goetia around age 25, and experiencing a pretty dreadful "getting your finger burned" as Jake tend to call our lapses in maintaining good protocol with them.
You also get difference manifestations depending on the ritual protocols you are using. well as the ritual we are using. Daimons approached through the Lesser Key are more cerebral and surreal. Using Verum they are much more solid, also darker. I imagine they are more like cerebral, thoughts, when using the modern ‘transvocation’ style of evocation like GoM. But I hear that works well too. You call even them while thinking they are aliens, they will appear as UFO and little grey men.
It really depends on what you’d like to experience. Keep your promises and you will be fine.
