When a medium/clairvoyant communicates with spirits, most will go into a meditative state and connect to divine source (the level where spirits reside). Within this process, they will communicate with their Doorkeeper. The Doorkeeper is the one that lets spirit through, keeping out negative souls/entities and only letting in positive energies and spirits. It is also the responsibility of the Doorkeeper to only allow one spirit in at a time.
Within the spiritual world, there are rules that both sides should abide by. For example, both spirit and person must respect each other when communicating. A spirit can put physical discomfort on a medium, to give evidence to the person receiving the reading, but the medium can request the energy/spirit take that discomfort away and it should comply. The medium should also respect the spirit world and cannot demand answers.
With all the clairvoyants and mediums we have talked to, all have said that they will get snippets of information and visions, and cannot have full conversations like two people would have. This leads to the question as to why this is the case. Is it that that the Doorkeeper prevents us from knowing too much about the other side?
There was an interesting hypothesis by author and paranormal investigator John E L Tenney (also known for the TV show Ghost Stalkers), saying that when on investigations there was only so much information we can get from spirits, believing that there may be an entity or spirit that prevents them from giving us too information. He also went on to say that maybe the reason for this, is because we as living beings are not allowed to know what is beyond the living realm. If we did know, there would be a lot of people that would wonder what the point of this life is and would want to go to the afterlife sooner than is ready for them.
Life can be difficult at times, we face so many struggles, but as some believe, these struggles are lessons we must learn from and should make us stronger and more compassionate; not give up and become less caring and unsympathetic to others. Depending on how you learn and grow as a person, some say it determines the level of afterlife you go to, or if you are going to be reincarnated.
