Hi there,
I am sure I introduced myself somewhere a while ago, however ill health has kept me away from the boards of late. I hope you don't mind me putting in my two penneth worth with regards this subject.
I find that doing ANY form of spirit work is aided by asking for guidance from our gaurdians, ancestors, teachers etc. Ouija board work is just the same as any other form of spirit contact in the sense that you cannot guarantee what/whom you are bringing through. Due to this, I always choose to ask for protection for myself, any other participants and for the space in which we are working.
During the time we are connected with spirit or any energy form, I always like to treat them with utmost respect - just as I would with anyone in this realm. I always give thanks for the energy/information they have given to me and wish for them to always be surrounded in positive light.
I close down by thanking guardians an guides etc for their presence and protection during the communication just completed and I ask that they clear my aura, the auras of the other participants and that of the space in which we are and fill our auras with positive energy only. Again I thank them for doing this.
I will say that you trust 100% the people that you are working with, that alcohol or any form of drugs are not involved, that the people you may work with are not currently unwell or suffer depression/bipolar etc. I will also say that you bring a halt to proceedings should anyone feel greatly uncomfortable/fearful/or have negative feelings/anger/the urge to harm themselves or someone else etc. I say this as the way people feel can effect the others around the board and false readings will occur.
Take everything slowly and make sure you open and close down properly, use protection and everything should work out fine. Good luck
If you find this of use and need some simple words to use, then please message me and I will write the words I use for spiritual work.
