The Narrow-Mindedness of a Miser
A miserly individual tries to block others from knowledge. He believes that he is deriving an advantage from his deed, unaware that when the knowledge becomes widespread and more people become familiar with sciences and knowledge, they will have a role in the proliferation of knowledge in society with their mental capabilities. It will be an advantage for everyone, even that miserly individual. So, the miserly and the jealous individual harms not only himself but the universe with this deed, and, unfortunately, he is unaware of this notion.
