Evocation (spirits, thoughtforms, etc)

So we've already talked about the Art of Evocation.

What is Evocation? It's "the act of calling or summoning a spirit, demon, god or other supernatural agent, in the Western mystery tradition".

This is one of my favourite style, so I thought I'll ask You:
Have you ever tried it?
Do you have any experience in summoning?

Hi Primus. Thanks for your post. I have been working towards learning evocation under a system of the Western Mystery tradition. It has been a challenge, but worthwhile. I have had success working with evocations under other traditions, with the help of others, and that, for me, continues to be a learning process. The most difficult part personally has been learning the structure and order of ritual. But, it is rewarding.
