Clairvoyance, produced from a 17th Century term that means clear vision, is a type of ESP - Extra Sensory Perception. Although usually used to describe a number of psychic abilities, such as second sight, telepathy, prophetic thoughts and psychic goals, it is strictly speaking the capability to discern information about a person, object, place or event by means of perception other than from the usual five senses. A person gifted with this particular ability is called a clairvoyant - a person who views clearly.
In parapsychology, the word clairvoyance is used purely to spell it out information - in the the present time and not really readily accessible to the actual clairvoyant - caused by an external source, instead of telepathy, where information is moved from one mind to a different. In other words, a clairvoyant has the ability to see or perhaps visualise events, things or persons away from capability or selection of physical sight.
Remote viewing, usually a controlled, specific process, is really a facet of voyance amour gratuite, as is clairvoyant dreaming. For instance, chances are you'll dream about a location they have never seen before and later on find it is exactly as they had visualised it inside their dream.
This became of me, for example, when I was about to start my own first term at college. As I had never visited the city where the university was located, my Father offered to take me there in order to find the way from the train station for the college. Having imagined about it the night prior to we went, I had been able to lead him to the school along the shortest route possible, knowing wherever and when to turn. I was even able to simply tell him how long it would take us to get right now there.
However, outside of the industry of parapsychology the term is often used to describe other types of paranormal, or anomalous, perception. Generally, it is used in relation to its the perception of past (retro cognition) or future (precognition) events. This can be a gift many possess without even realising this. To use another personal expertise as an example (and I don't claim to be a clairvoyant in any way), a few years ago, a friend's daughter had gone into hospital early in the evening to have her first child. Although with a group of shared friends around 10 PM, somebody suggested we should phone the hospital and find out just how she was getting on. As one of them picked up the phone, I declared that a call would be wasted, as she had have a little boy in early hours of the following morning. We known as anyway and were told she was sleeping as the labour acquired slowed. My friend explained to me the next morning which her grandson came to be at 5:30 AM.
Frequently, mediums will also refer to the actual perception of images identified during communication with spirits as clairvoyance.
In any case, clairvoyance is a precious present which can and should be utilized in order to help as well as guide others.
