Clairvoyance is about seeing clearly into the etheric realms.  Clairaudience is all about the hearing the whispers or bellowing from the etheric realms.  Being a clairsentient is about feeling those in the ethers reach out and touch you.  This is different from being an empath.  Empathic people have the ability to feel what others feel. Sometimes it takes a lot of self discipline to learn what is your emotion and what emotion belongs to another.  Empathy can also be a physical sensation.  If you are a person with this ability, do yourself a favor and learn how to transmute ‘the not your’ energy or emotion to neutral and then move it into something beneficial.  Unconditional love is always beneficial.
