What’s wrong with being rich (or wanting to be rich)?
It shows that you’re too invested in the material world. The visible world is fleeting and illusionary, so concerning yourself with money, its perceived power, and the hoarding of trinkets, demonstrates a lack of understanding — it’s focusing on a mirage.
Rather than valuing shiny things, value the contentment of others. Do engage with the world, but from a lighthearted perspective — favoring cooperation over competition.
Those focused on illusion are lost in their confusion, while those focused on the contentment of others are themselves contented.
