You cannot impose a culture from the top--it must come from under. It grows out of the soil, out of the people, out of their daily life and work. It is a spontaneous expression of their joy of life, of their joy in work, and if this does not exist, the culture will not exist. Joy is a spiritual quality, an impalpable quality: that too cannot be forced. It must be an inevitable state of mind, born of the elementary processes of life, a by-product of natural human growth.
