The purpose of this book is simply to show that the problems in the world do not lie in the external environment and those inhabiting it, but in our own mind. Our attitudes will affect others positively or negatively. Therefore, we must try to abandon negative thoughts, such as greed, anger, lust, attachment, and closed mindedness. And develop beneficial attitudes, such as love, compassion, kindness, and forgiveness. In this book, I do point out some negative aspects that we are currently facing in the world. My intention is not to make any of us sad, discouraged, or upset, but to really illustrate how our actions and way of thinking truly affect us and the world. In doing so, I hope that we choose to become more aware of our thoughts, speech, and actions. And to aspire to become good human beings who function well in society and live harmoniously with others.
