The universe has provided us with the natural laws that govern our universe. Cause and effect of everything we do in life: the good and the bad. When you understand how to work with the laws your life changes for the better and you now are always aware of choices you make and how to improve any area of your life. Understanding how Natural law works and why it works, can help with understanding Mediumship. The process of understanding the reason why things happen to individuals, emotionally and mentally defines how a medium can work. Being able to recognize our true self as source, but always aware of our balance during all of the emotions we carry. This does allow us to direct the thoughts so as to be positive and clear so as to work with source (our higher self) to be able to connect to source, to allow what is needed to do the work.
The unexpected can possible happen, but it is truly not unexpected. Even though we live with thoughts every day, the outcome of those thoughts are in constant motion. The thoughts dictate the outcome of what we experience. Positive thoughts directs the energy in a positive way for positive outcomes. Negative thoughts beget negative outcomes.
