Joy is the perception of beauty, unlike happiness, which is because of something. Joy is singing of the heart, a feeling of praise.
I see the way of the artist as a kind of pilgrimage. When you go on a pilgrimage, you set out from where you happen to be and start walking toward a place of great sanctity in the hope of returning from it renewed, enriched, and sanctified. However far you may walk, every pilgrimage is a safari into your own dark interior, an inner journey. For pilgrimages belong to the inner world, to the realm called the "religious."
