@sree251 The boy viewed the world through a lens of amassing material possessions. To him, "treasures" meant physical objects to collect and own. This limited lens led to confinement, emptiness, and eventual disappointment. The girl was able to gratefully acknowledge the little that life may offer. She used the can as a frame to focus on the beauty already existing around her. Her lens turned the ordinary world into an endless supply of wealth. Mine is the point made by Napoleon Hill in his book, Think and Grow Rich: true abundance is not about what you can gather and hold, but how you choose to focus on and value the world around you. That is the "lens" through which we can more properly accumulate the riches this world has to offer.

Ok, but what is this lens? If it is a figure of speech, then it is just a metaphor.
