The greatest minds will stop to wonder,
The morose spell that I cast asunder,
Sometimes, there is great joy that I can bring,
Or cause thoughts that swirl in a mental din.
The symbols of love and logic, divided,
An essential respect for each, abided,
With fear or dread I am often met,
And faced with hope to not be misled.
But with me, to understand, you must,
I'm not always a cause for boom or bust,
Equally, peace and delirium may be found,
But only upon a champion's espouse.
A trivial matter or a grave proceeding,
Can you articulate this riddle's meaning?
