Everyone wants a happy life without difficulties or suffering. We create many of the problems we face. No one intentionally creates problems, but we tend to be slaves to powerful emotions like anger, hatred and attachment that are based on misconceived projections about people and things. We need to find ways of reducing these emotions by eliminating the ignorance that underlies them and applying opposing forces.
In today's materialistic world there is a risk of people becoming slaves to money, as though they were simply cogs in a huge money-making machine. This does nothing for human dignity, freedom, and genuine well-being. Wealth should serve humanity, and not the other way around.
When we are angry we are blind to reality. Anger may bring us a temporary burst of energy, but that energy is blind and it blocks the part of our brain that distinguishes right from wrong. To deal with our problems, we need to be practical and realistic. If we are to be realistic, we need to use our human intelligence properly, which means we need a calm mind.
Just as rust, which arose from the iron itself, wears out the iron, likewise, performing an action without examination would destroy us by projecting us into a negative state of existence.
