Difference between a "mediumistic reading" and a "psychic reading" by Joanne Gerber, LLC - Psychic Medium and Spiritual Teacher:
If you are looking for guidance about your life, such as career, realtionships, spiritual growth, etc., then you are requesting a psychic reading. I will connect with you "energetically", by working with your aura, which contains information about you, your past, your present and your future. It is my spirit in my body connecting with your spirit in your body.
If you are looking to connect with someone who has passed, then you are requesting a mediumistic reading. I will raise my vibration, as those in the spirit world will lower their vibration on a frequency level to make the connection possible. It is my spirit in my body connecting with a spirit that no longer has a physical body.
From the Aberdeen Bon Accord Spiritualist Church:
The difference between a Psychic and a Spiritual medium is the fact that a Psychic will read from you (your aura) and can give you quite specific information about you and your life, whereby a spiritual medium will endeavour to make a link with a person you have known or loved who has passed on to the spirit world.
...we are physical beings who have a spiritual energy which animates our physical bodies and because of this we ourselves radiate an energy field around us known as the Aura, this aura allows us to feel things from one another at times and even though no words have been spoken, we can often know how a person is feeling. I am sure each one of you at some point have experienced this. Our aura contains a sense of all our thoughts, feelings and experiences and there are individuals known as “Psychics” who have the ability to see or sense the aura and can interpret this information and give us a Psychic reading. This reading will usually contain information regarding who we are, how we are feeling/thinking and perhaps a little about what is happening in our lives at that time.
Although many Spiritual mediums also have the ability to sense or see the aura, they will endeavour to use their own aura to reach out and to try to make contact with a person in the spirit world who you know or relates to you and should be able to provide you with enough specific evidential information about that person e.g. physical description, relationship, personality, nature of their passing, hobbies, habits, shared memories and even information relating to things that may have occurred since they have passed to enable you to know without a shadow of a doubt that your loved one is still very much alive and well in another realm of existence.
From Wendy's Sunny Days:
A psychic will 'read' the person (sometimes called the sitter) in front of them. By tuning in to someone's aura (this is the energy field around them), a psychic can pick up certain information. This is because our thoughts, feelings, emotions, desires, and fears are all recorded within this field, and since our thoughts can change daily this is one of the reason's readings can be quite different if received only a few weeks or even days apart [Thus one of the reason's it is stated that we 'create our own reality'].
A medium will make a connection to the Spirit World in order to provide evidence of survival of the Spirit beyond the Earth Plane. No tools are required to be able to communicate with a Spirit mind, other than the ability to raise one's vibration/energy to a higher frequency.
