A rare experience of a moment at daybreak when something in nature seems to reveal all consciousness cannot be explained at noon. Yet it is part of the day's unity.

My doctor explained that exercise and diet changes might help and that I also might need a medication.

Design can never be an ultimate explanation for anything. It can only be a proximate explanation. A plane or a car is explained by a designer but that's because the designer himself the engineer is explained by natural selection.

As for everything else so for a mathematical theory: beauty can be perceived but not explained.

I do not have much patience with a thing of beauty that must be explained to be understood. If it does need additional interpretation by someone other than the creator then I question whether it has fulfilled its purpose.
