Clairsentience is used both for paranormal feeling and paranormal knowing. With paranormal knowing, the person gets through an answer. With this answer he got the feeling / knowing to be absolutely sure the answer is correct, without being able to give a rational explanation. The (clair) knowing perhaps seems to come from nowhere, it doesn't come from a feeling or intuition, but comes from "nowhere" so it seems.
When a person is pure and doesn't influence the answers, he gets objective answers. But impurity or influencing can deform the answers. A person with clairsentience abilities doesn't get the answer from his/herself, but from a cosmic source of information. The things the person gets through aren't words or images at first, but is a universal energy that the person in case translates to his/her world in his/her language of images. The translation happens without thinking of the person and happens automatically, unless there isn't any word for it or can't be imagined. When there do exist words for (with the right nuances) or there exist images in what it can be translated, the person gets this through before he thinks about it the answer or what the answer might be. Often during phrasing the question the answer already gets through.
Spiritual.com.au - Bringing you Love, Light and Wisdom provides two definitions:
Clairsentience - Prophetic (1)
This is a person who will pick up a thought and just knows it. This person is sensitive to precognition and has hunches, dreams and knowings and this person usually deals with the future or present and how it will affect another. If you were to meet an enlightened Prophetic you would be able to get some information about your 'line of probability', tomorrow is not set in time remember. This could be a person who has a dream about something and that dream turns out to happen in reality. They have the ability of prediction because they 'just know' and can tune into and understand their hunches.
Clairsentience - Feeler (2)
This is a person who will pick up a thought and transform it immediately into a feeling. This persons life can revolve around how it feels to them. Their sense of touch is well-developed and they have the ability to know people by feeling what they feel. After enlightenment, this is someone would have the ability to practice psychometry. The ability to put something belonging to someone in their hand and read the energy. Depending on their other gifts, they could tell the past, present or future from the energy. They have the ability to feel how others feel but only on the emotional level. They will be able to not only empathise but experience their pain, loss, grief etc. For instance, if they were to channel energy from a persons past life they would experience the pain and hurt that that soul experienced in that past lifetime.
