All the things that have ever deeply possessed your soul have been but hints of it, tantalizing glimpses, promises never quite fulfilled, echoes that died away just as they caught your ear. But if it should really become manifest - if there ever came an echo that did not die away but swelled into the sound itself - you would know it. Beyond all possibility of doubt you would say 'Here at last is the thing I was made for.'
