Ngurah strongly feels that art is produced by two kinds of artists. The pelukis is an artist who works solely from his or her brain, hands, eyes, and heart. The pelukis is not only prolific as a technical artist, but works from inspiration and manifests his emotional ties to the world. The other is the tukang gambar who is an artist that is successful in rendering an image or motif based on a concrete visual, however does not rely on emotions or spiritual inspiration for their work.
