Clairvoyance
is the ability to see energy in forms, shapes and pictures. It is also the ability to see into a person's body, picking up what is happening and manifesting behind the scenes, what is coming toward the person, and the ability to see fairies, guides and angelic energies.
Claircognisance
happens when people just KNOW, without ever seeing or hearing guides or angels.
Clairaudience
is the skill of communicating with the spirit realm via sound, hearing energy as if tuned into a radio station. What one hears sounds different from one's own tone of voice, sometimes even having a foreign accent. Blessed are you when you hear the angels singing in your ears! It is a sound unheard on this planet. Most people who have a "developed" ear are very sensitive to noise and prefer sounds that are soothing.
Clairsentience
is the ability to feel energy in your body as it is happening. The clairsentient person can feel the mood of another, as well as the energy flow in spaces such as offices or houses. This skill can be developed and deepened so that one becomes able to intuitively access levels of soul.
