The spontaneous emergence of ideas, images - this is imagination. It cannot be perceived through the senses. Very often I have to turn on my imagination to paint a picture or write a beautiful story. When you start to imagine what will be in the picture - a million ideas and imaginations come to mind. Sometimes I can't figure out how to paint my work, then my imagination comes to the rescue. Imagination can usually be swallowed while sitting in the open air, watching other people reproduce their art. Imagination is something without which each of us cannot fantasize. It is part of our life.
