Clairvoyance, based on a 17th Century term which 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 ideas and psychic desires, it is strictly speaking the power to discern information regarding a person, object, location or event via perception other than through the usual five senses. A person gifted using this ability is called a email - a person who sees clearly.
In parapsychology, the word clairvoyance is used purely to spell it out information - both in the present time and not necessarily readily accessible to the 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 visualise events, objects or persons outside the capability or array of physical sight.
Distant viewing, usually a managed, specific process, is a facet of voyance gratuite, as is email dreaming. For instance, you might dream about a location they have never seen before and then find it is exactly since they had visualised it in their dream.
This became of me, for example, once i was about to start my own first term in school. As I had never frequented the city where the school was located, my dad offered to take me personally there in order to find the way from the train station to the college. Having imagined about it the night just before we went, I had been able to lead him to the school along the shortest course possible, knowing wherever and when to turn. I was even able to tell him how long it would get us to get there.
However, outside of the industry of parapsychology the term is frequently used to describe other sorts 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 have got without even realising it. To use another personal experience as an example (and I don't claim to be a clairvoyant in any way), a few years ago, any friend's daughter went into hospital early in the evening to have her first child. Although with a group of common friends around 10 PM, an individual suggested we should phone the hospital and find out exactly how she was making. As one of them picked up the phone, I announced that a call will be wasted, as she had have a little boy in early hours of the following morning. We referred to as anyway and informed she was asleep as the labour acquired slowed. My friend explained to me the next morning in which her grandson was created at 5:30 AM.
Frequently, mediums will also refer to the actual perception of images identified during communication along with spirits as clairvoyance.
Whatever the case, clairvoyance is a precious gift which can and should be utilized in order to help and also guide others.
