Fiction writing is not about language.
It is about experience and feelings, and where do experience and feelings lie? In the body. Nothing is more human than the body, and few things are more confounding than the passions that lie within: everything from the most tender love to the most murderous rage. Therefore, if as writers we are to explore and express the human condition, we must approach our task through the body, not through the mind ―  through experience, not through words. This doesn’t mean you have to go out and literally experience everything you write about. That’s what the imagination is for. You imagine and the characters unleashed from your creative unconscious live the life and through them, you live it, too.
