Clairvoyance, where you see images, objects, people and scenes presented to you in your mind's eye. For this it's best to build up a bank of symbols (archetypes) for spirits to present to you that represent certain meanings to you. Your mind is an open book to the spirit world as long as you allow it. Your personal language of symbols and their meanings is accessible to them. As an example, if you decide that a horse represents freedom to you, if spirit shows you a horse then the topic is going along the lines of the client needing more freedom or gaining more freedom. Other accompanying symbols should clarify this.
The power of the mind, when it is NOT controlled by the conscious awareness of the owner, receives suggestions every second of the day about how it should think, act or respond — impulse. The individual is nothing more than a puppet controlled and programmed by an out of control, chaotic mind. When a being develops awareness and becomes conscious about the events that are taking place around them, they can decide what information to allow in and what information to eliminate. Thus, they become responsible for their life and everything that takes place within it. They no longer require someone to tell them the answers to their questions about probable outcomes, they know that they have the power to create the outcome based on the thoughts and actions they project. They are now able to consciously manifest the life that is in alignment with their dreams, based on their sincere intent and the impeccability of their actions.
It’s simple — because they can! People on the Other-Side want to share our lives with us. Over the years I’ve been practicing as a medium, I must have done thousands of sittings where spirits have come through to acknowledge that they were around their loved ones during difficult times, and by doing so, they were able to lend their support and strength.
