Mediums work with spirit! Mediums are like the piggy in the middle twixt the spirit and the sitter. The medium links in with spirit and passes on the message to the seeker. The go-between if you prefer.
We cannot, as mediums, demand who comes forward to work with us, but we can ask. We ought not ask for a particular spirit as there may be others who are very keen to communicate who might not get through.
As mediums we should work really hard to get through as much information as possible to do the spirit world justice. We should not settle for a simple sentence or two. The more evidence the better as that is the only way to prove survival to non believers.
If you are a spirit worker you must set your sights high and never be satisfied. Only then will you get communication worth the wait. If the spirit that your sitter wants does not come through you may still get good proof from another loved one. Don’t think for a minute that our spirit loved ones have nothing to do, but to roll around heaven all day!
