A thought for discussion,
Did you realize that you can talk to past loved ones as a medium and talk to living people spiritually? The word Medium is not limited to dead people but references the ability to understand and use the spiritual communication system.
For instance, you are thinking of someone who suddenly calls you. Thinking of something, and then your partner says the exact words as your thoughts. Knowing someone is ill before they tell you or even knowing your baby will wake up before they do.
These are all indications of spiritual communications without doing anything physical. So if you are suddenly thinking of some who is alive, this is also a mediumship ability.
We are all mediums. We all talk to past loved ones and also the live ones without speaking. It is our spiritual body doing the work and hoping we will pay attention.
