Just as physical energy acts upon physical objects, psychological energy would act upon psychological entities, i.e. thoughts. Psychological energy and force are the basis of an attempt to formulate a scientific theory according to which psychological phenomena would be subject to precise laws akin to how physical objects are subject to Newton's laws. This concept of psychological energy is completely separate and distinct from (or even opposed to) the mystical eastern concept of spiritual energy.
Maria Medium sends hundreds of emails. An online tarot reading should never cost $79! When I was testing this site, I created three alternate identities. For each of my three identities, I chose a free three-card tarot reading, but the site demanded my name, email address, and birth date—information that real tarot-card readers never need or ask for. If you confirm the email, get the reading/sales pitch, and ignore it, Maria's urgent emails will follow. And all three readings were identical.
First, it is important to know what differentiates a true psychic medium. Mediums are clairvoyant, but not all clairvoyants are mediums. What that means is that all psychics have clairvoyant abilities and they are able to tap into energetic fields around you beyond the daily world that we live in. But some special clairvoyants also have the ability to communicate with the dead, animal spirits, angels or other messengers.
