There is never any end. There are always new sounds to imagine, new feelings to get at, and always there is a need to keep purifying these needs and sounds so that we can really see what we’ve discovered in its pure state. So we can see more clearly what we are. In that way, we can give those who listen to the essence the best of what we are.
