It saddens me to see such bigoted and blinkered views about how mediumship should be demonstrated or practiced
Especially when it comes from those who should know better and claim to hold the key to the safe that stores the rule book for communicating with the spirit world
In actual fact the key, the safe and the book does not exist except for in the minds of those people.
So what is Mediumship?
Mediumship and all its derivatives is firstly about learning to understand your own spirit and understanding that you are a part of the bigger picture that contains both incarnate and discarnate spirits
Whether you focus on angels, guides, Buddha Christianity, Catholicism etc, it matters not. It is your journey and yours alone.
If you choose to share it you must expect differences of opinion, that is what makes the world go round, but you should stay true to yourself and accept the differences.
