Can I ask a question here? What is/are the purpose(s) of summoning a 'spirit' ?
Marto
As far as I've seen it discussed and done (and done it myself, in extremis/foolishness)
1. bragging rights
2. guidance
3. protection
4. information
5. communication
6. carrying (intent, purpose, message, apology)
7. curiosity
8. access to higher forms and realms
9. access to lower forms and realms
There is a difference between beings one summons and beings one creates, but they often seem to serve the same functions, as least loosely. It is generally considered unwise to try to summon beings who are tied to place, unless one goes physically to that place first. That alters the dynamic, however, and one will more often be petitioner in those circumstances than equal or (temporary) superior.
There is generally some kind of exchange involved - how burdensome this is is usually dependent on how good a negotiator you are, or what previous relationship might exist between you or your family (band, clan, etc.) and the being.
Like astral projection, actual communication with such beings is rarer than it seems when you read about it on boards. It is very easy to fool yourself, to have a third-person daydream and decide it was a communication with the 'unseen', or to write both parts of the script and convince yourself that the second is actually happening spontaneously.
It does occur, though. (You can't commit me, I've moved

) Like any such experiences, however, I advise reality checks throughout the process and afterwards. Especially afterwards - before acting on any information received, in fact. If you do it to learn something otherwise unavailable to you, and you do in fact learn it, you will find that things that were uncheckable when you tried to research them from the 'front end' will be more easily checked from the newly acquired 'back end'. This is my experience, at least.
The foregoing is offered up with full understanding of how unprovable and insane it sounds. I don't recommend people do evocations or invocations casually, but most of our information on it does come from people who were willing to try it out. I'm sure the apprentice gunpowder researchers of old learned much from the smoking craters their masters left. (or vice versa)
