Managing a Spiritualist Center
Every spirit communication will be different, so conformity is impossible.
Just as every physical person is individual and different, so it is with spirit.
Once you have mastered attunement and can bring messages forward from spirit, just relax with this energy and let is flow.
Do not judge what you are getting or try to apply your own ideas or thoughts to the message - as the message may not make sense to you, but will be perfectly understood by the receiver of the message.
Above all, enjoy this experience and have fun with it. Spirit loves laughter and finds it easier to work with and more appealing to attune to uplifting energy.
