Can not be used as an answer in art. Expression in art or artistic expression is a new genre in expression. Called new because of the expression in the words translated into processes and processes that have to endeavor to achieve it.
An artist will not be directly or spontaneously able to manifest his work due to fear, anxiety, joy, sadness and so forth. The feelings he experienced must be suspended first (made object) into a memory, memories and experiences for him.
When the feeling is already processed by the artist into the object, then in the current mood, feeling full of passion in the work and art, the artist can realize his work. Works of art that are born using a process that will bring universal values, which others can feel as well as what ever experienced by the artist.
