Hello Teosanru, the sigil often indicated is a triangle (2 pts up, 3rd pt of triangle with hooks at the bottom) with an X over it, although EA mentioned that there is another more intense way not using a sigil- which I think will be in the Evocation Course.
try a search on this forum, or on a web search engine sigil (ie “Lucifier sigil” … in say google… ok I just went and did that… this one
[ http://www.symboldictionary.net/?p=1342 Sigil of Lucifer (“Seal of Satan”) ]
but the best way is to perhaps - A) learn the oldest source of the being indicated (ie EA’s writing about seeing earliest form, like Beelzebub… vs going back to Bael-z’b… being not a demon, but a Sumer-Mesopotamian God)… it seems the concept/personae you are calling affects (like different Hats people wear, ie how you address-greet someone can put them in “manager-mode” or “friend-mode” or “parent-mode” let alone defensive-mode vs friendly-mode, etc.
-this being put of the prep immersion (which it seems you are doing, just to mention it seems the how-who calling affects, but doesn’t Shape (above example doesn’t mean any person will be how you want depending on how you think of them- ie some MagickalWriters ~its all in your mind.
so A) the who calling, and B) call (ie in addition, or rather than using any sigil, say-speak the name… and as EA wrote (in something, not sure where):
“It is not enough to speak out loud, the words must be spoken directly to the audience. While it does not require meditation and trance concentration, it does require the peculiar attitude of speaking to someone who, at the beginning, is not apparently present.”
A&B … and then pause and C) listen and see what responds (just like calling a cell/mobile# just cuz they don’t answer right-away doesn’t mean its the wrong#… and phones work pretty well, while we need to “re-wire” our systems to ‘make the call’ and to ‘receive clearly ~hear them’
from Questing After Visions
in Tome p524 (QAV Ch5): “Opening the Doorway- all the power and abilities of the Master rely on this ability; to turn his Attn inwards, to be silent, and to listen.”
–p527: “Hold your inner view of your enviro until it attains some level of clarity and stability. Your Attn will begin to leave your phy body&world and will transfix on the spir. … It is your ability to remain in Th, yet still to consciously activate your spir-sight, which triggers the G-jump…
good luck- and the frustrating process may be gradually preparing yourself (as an ex, your seeking has begun the call, clues to further Contact (even if from other “people”) actually clues from that Entity?)
