Nice! That's not quite it, but it's close. Clatter is used to represent the noise of the busy world, all the things in life that keep you busy, distracted and not focused. The quiet represents the focus in life, the clarity apart from the distractions. The whistling is the calling to that clarity that you, so often ignore in life.

Choosing to take that stand and focus on the clarity and "silence" when being called is a tough decision because it may mean you have to change what you're presently doing, amidst the noise and "clatter".

Finally, the question is... does all that clatter really even have any meaning - your destiny is the calling - the quiet, the focus.
