The Spiritualists' Handbook explains everything you need to know about Spiritualism in easy to read style. It tells you the history and philosophy, about seeing,  hearing and feeling those in the world of spirit, how to develop your own mediumship and psychic abilities, answers questions like is it alright to disturb the dead - where is the spirit world - can you tell the future - what is spiritual healing and much more.

As Lyn says in the book:
 
"A medium has to have a good psychic ability, but someone with good psychic ability isn't necessarily a medium. After all, a medium has to heighten their awareness to a pitch, and tune in to a level where communication from the spirit world, which exists on a much finer frequency than our own, is able to take place.

HOW IS IT DEVELOPED?
Everyone is psychic to a greater or lesser degree.
The vital spark that animates us isn't just linked to the average five senses, but is definitely connected to the sixth, our earthly intuition, sometimes called our extra sensory perceptiveness or ESP.Lyn tells you in detail how these gifts can be developed to a greater or lesser degree by anyone.

A PSYCHIC IS NOT NECESSARILY A MEDIUM
A psychic uses this intuition to 'read' body language, which includes facial expression, what the clothes a person wears 'say' about that person, as well as the electromagnetic and emanating energy fields around others known as auras. By linking in to the material energies of the world around them, psychics can gather relayable information about someone's life. And given that information, psychics can not only make some quite accurate assessments of an individual's emotions, state of health and past and present state of affairs, but can also project some possibilities about the outcome of future events. It has to be said that this is invariably a misleading practice given the scientific laws of probability. Psychics who work in this way have not developed their abilities to enable themselves to tune in to the spirit world, but they may sometimes have a clairvoyant capacity which would lead someone who was asking them for advice to believe that they were actually consulting a medium.
However, in this book, Lyn tells you how to develop your own psychic abilities!

TRUE MEDIUMS
Now a medium, like the psychic, is naturally sensitive to energies which may go unheeded by the majority, but a desire to transcend the mundane spurs the would-be medium, who through undertaking much meditation and training learns to identify emanations coming from the discarnate dimension - the world of spirit.

As mediums develop this talent they become aware of the distinctive vibrations separating and distinguishing their helpers, sometimes called Guides, and they also learn how to control and use their faculties to become a good and clear channel for other discarnates in spirit who are existing on other planes.

One of the most important aspects in the development of mediumship is to be able to differentiate between gut response or psychic intuition, and a positive link with a spirit communicator."

The Spiritualists' Handbook contains instruction for the would be medium and the already working medium in entertaining and easy to understand style.
There is a comprehensive section on healing and Spiritualist ministry. There are stories about healing and mediumship with codes of conduct and templates for common services such as Marriage, Wedding (and same sex) Blessings, Namings/Baptism and more...
