The first time when I was "playing" the spirit of the glass was when I was at the age of about 17 or 18 years, maybe 19, I cannot remember exactly because it's about 10-15 years ago.
Nevertheless, I practiced this frequently for almost 5 years, more or less 1 time a week.
The circumstances I approached to this were comparatively good, since I have been introduced by my grandmother and by my youngest aunt, both very experienced at the whole topic for their lifetimes.
So from the beginning I knew quite well about the risks, possibilities, "safer-use" and so on. All of these are really very important, since this is definitely NO GAME and you should only do this if you know what you are doing, if you are good-minded, have a strong personality and if you are not-too-easy to be influenced.
I would like to explain to you what I have learned back then and what has proven for me to be definite reality and fact!
We used a square wooden board and drew our alphabet plus numbers from 0 to 9 onto it, all of those in a circular shape.
Besides, we created small fields saying things like "yes", "no", "hello", "goodbye" or whatsoever.
We used a glass (for instance a wine glass with a long neck would do the job pretty well) and placed it top-bottom onto the board.
It's important to have at least one fellow with you, since this should not work if you are alone. If it works when you are alone, then you will most probably have called a so called "bad/evil" spirit, so in this case you should stop what you are doing!
All of us placed our fingers onto the glass and literally "called" a spirit.
When the glass started moving;
First of all, we always demanded a prove that the called spirit is really "good" or he/she is really the one we wanted to call; for example we let him/her draw a (holy) cross onto the board (for Christians), or ask him to move to a corresponding combination of symbols we have always been using for "identification".
If the spirit refused to give the proof: HANDS OFF the glass!
If the spirit gives you the proof to be good-minded or to really be the one you wanted to call (if it is that particular frequently called spirit, then you will just know), go on talking to him/her; be as polite as you expect him/her to be as well. Ask for his/her name (and history,...), why he/she is there and what the matters of his/her concern are, before you start asking any personal questions and similar!
In other words, show the "spirit" that you are interested in him/her and listen to what he/she wants to tell.
ALWAYS: prove your good trust before taking any risks (of wrong or misleading answers or of ending up fooled and annoyed by hard-to-stop hauntings in your home or whatsoever), each and every time!
It's also important to be careful about asking questions that might "prove" the authenticity (I don't mean his/her identity, I mean a proof of true existence) of the spirit too much, as these questions might make him/her angry or disappointed in any way - same like every human being might get annoyed when being asked such questions too much.
So who is actually "talking" there?
From a physical point of view: only yours and your fellows' fingers are moving the glass - nobody else.
From a spiritual point of view: the spirit "guides" your fingers to move the glass to the position he/she desires.
(only my opinion!)
As of my knowledge, it is important that you create your board on your own. Don't buy any pre-made boards from the store (like Ouija-boards for example; beware of using Ouija-boards anyway, I've never heard anything good about them and I've never used one. Ouija is something different than this.)!
If you take your time to manufacture and paint your wooden board on your own, then all the energy/emotion you spend on it will be kind of "bound" to that board. (again, only my opinion)
So to say, if you are a good minded person/spirit, that board will attract mostly good-minded spirits, since this is YOUR board!
This is also only my personal opinion and it is not, I repeat: NOT! A guarantee for "safer use" or "positive contact".
We have had a couple of "evil" spirits on the board in the past, and sometimes it might be fun talking "nasty stuff" with them, but it's not advisable to push this too far.
Before you even start using a board like this, you must be sure to know a way of how to cleanse the location and especially the board, to make a possibly evil spirit leave again!
As I mentioned above, this post is NOT a guarantee for anything and it is NOT meant to be a tutorial or manual of any kind.
This is just a report about my experience about this topic!
I will go on telling more about that in a "Part 2" of this post.
All the best:)
