Summary
This quote implies that the influence of gold, metaphorically representing success and wealth, has a contrasting effect on different types of individuals. It suggests that those with strong and noble characters - represented by "great souls" - are inspired and enriched by wealth, much like how the sun melts wax. On the other hand, individuals with weak or brittle characters - symbolized by clay - are hardened by material riches. Ultimately, the quote suggests that wealth can either magnify the inherent goodness and greatness within individuals or expose their flaws and weaknesses.
