Can we understand it this way too?

Gold sparkles as the daylight when it has gone through a section of high intense heat in the fire furnace. The Goldsmith passes through hell of heat putting in a worthwhile effort to refine the raw gold, then beaten to form adorable instruments.

Just like the Goldsmith passes through hell of heat, we might have to confront heaps of issues, that might seemingly cause us to drop down our hands, a way to surrending to defeats.

The darkness is what really shows us who we are. It is our darkness that tests our virtues and brings out our true character.

Through the hell of heat, the Goldsmith endures. The Goldsmith's darkness is the endurance he shows through the section of high-heating the raw gold to what becomes adorable instrument(s).
Similarly, our darkness test our virtue and brings out the very best in us as individuals.

In turn, the endurance shown in our dark times builds or forms deep rooted love in us .

Thereafter, love lift us up and also help to accommodate others, thus, impacting the world positively, just like as the Goldsmith benefits at the end from the whole stress and other lovers of gold too.

Job well done @meditationmann. Thanks for organizing this @danielsaori.
