God’s signs—divine signs from which lessons may be learned—are visible everywhere, but most of us human beings move around in blind ignorance of them. I thought that the dog, being unaware of all that was contained in the books all around it, was similar to the way most human beings lead their lives. People are lost in the creation, and not in the Creator. God has given us wisdom, but we human beings do not apply it. For example, we seldom address ourselves to the biggest questions in life: “What is the Truth?”, “Who is the Creator?”, “What is the purpose of life?” and “What happens before and after death?” Man continues to be lost in the world of appearances, without even giving a thought to the real world. We should understand what God wants from us by understanding His divine signs and then lead our lives accordingly. We should remember that God expresses His mind in the Universe and that the Universe is thus full of divine intelligence. We must, therefore, observe it and extract spiritual lessons from it. It is wrong to imagine that one man can know everything by oneself. We need God, the Creator, to guide us here, as everywhere else, for the human mind is not sufficient. Without God’s guidance, man cannot acquire knowledge.
