In the words of Fairfield Circuitry:

Poolside conversations while staring at your own reflection. The
depths of which shall never be known, at least not for another couple
thousand years. So it goes.

Before the reflection, is the experience. Before phenomena, or even
noumena, is that which is undefinable. That which has never been heard,
that which will never be heard again and that which has always been
heard but never listened to.
