In working with the guides who assist me, I can connect with a number of beings. Some may require an aid to move to a different level. Others have a message for someone here. Each situation is unique.
The only goal for me during the event is to remain focused in light and keep an open heart. Everything else takes care of itself.
When cleansing a space, I have no need for someone to tell me whether there is another presence. The energy present can easily choose to become visible (in whatever form necessary) or not. A common theme is to undo my necklace.
My activities require I pay attention in my personal life as well. In recent encounters in my home while I was working on another space, I was reminded by my guides to keep my boundaries up even while I sleep. The spirit energy causing concern for another came to visit and assured me I could be caught unaware. There was a little demonstration to prove the point.
When I do my part, the guides do the rest. I was given a certain necklace. (A specific cross.) And the guides told me to wear that necklace to create a barrier. Until I put the cross on, my earrings were being removed. I would find them again but the point was made. It stopped after the necklace was on.
There are other hints and reminders that my world is not like the world outside my door. So whatever works for others is well and good. My guides have given me room to explore and expand all that I hold to be limitations. We have no clue our limitations until we exceed them.
