okay. Here is what you need to do:
Draw that sigil
Light candle and incense
Meditate and gaze on the sigil, and once you are ready. Chant the chants provided by vk.
Then once u feel presence ask your request. if you still dont feel. Try after vk chants, to chant the spirits ENN.
Then if you felt the presence, and made ur requests. Thank the spirit and give the license to depart.
After that, go take a shower or cook. just to get your mind of the ritual and go back to the mundane (mentally).
if you look into my topics, you will find an invocation guide that shows a little more in depth process. Also, feel free to check out my journal. It might have some information that helps.
