Mediumship is not 'chanelling' big spirits or archangels. It is speaking for the dead, for our loved ones who have passed on, leaving us behind. However, the medium can speak for your loved one to let you know they still love you and may have messages for you...generally of love and guidance, that benefit you.
Jude Starks is a first class pro with mediumship...what it is and what it is not and how it can best serve those who wish to contact and 'chat' with their loved one who has passed beyond the veil.
