What one can learn from this is the theory of the whole process of their spiritual development. By making God their Beloved, and by seeing God in the sublimity of nature, they create the presence of God. As the whole day's affairs in life consist of both joy and pain, so the life of the dervish is also filled with both joy and pain in the presence of God. By the help of concentration, of poetry and music, both joy and pain are felt more deeply. Therefore God becomes living to the dervish. His presence is before him in all his moods. When once his pain has had an outlet in some form or other in the sama, the musical ceremony, the condition that follows is that of deeper insight into life. Upon whatever object or person he may cast his glance, these reveal to his soul their deepest nature, character and secret, thus making the whole of life clear to his vision in the light of God.
