A man without meditation becomes mediocre. His consciousness gathers rust. His consciousness becomes covered with dust. He loses all brightness, all intelligence. Slowly, slowly, he completely forgets who he is. He becomes so stupid — it is the utmost stupidity to forget who you are.
And that has happened to the whole humanity. Through meditation, consciousness can be sharpened, dust can be removed, rust can be washed away. Your mirror can again become bright. And when your consciousness is bright it reflects reality. God is another name for reality. To know God is to know all; not to know God is to live in ignorance, darkness, death.
