Children are dreamers; they live in a world of fantasy, where anything is possible. Just ask a group of children what they want to be when they grow up and you’ll get some of the most fantastic, unrealistic responses imaginable. “I’m going to be an astronaut fireman, so that I can save people on the moon,” or “I’m going to become a great tzadik and learn how to speak every language so that I can teach Torah to everyone.” Children live within the infinite, the realm of endless possibility. However, as they grow up, they begin to experience the struggle of reality, where their notions of the infinite start being challenged. Imagine a young teenager lying on a grassy field, gazing into the nighttime sky. As he stares up into the stars, he thinks to himself, “Look at how enormous the universe is. The sky just expands endlessly. It must go on forever.” After sitting with that thought for a few moments, he becomes uncomfortable. “How can anything go on forever? Everything must stop eventually.” But after a few moments of ease, his thoughts intrude again. “But how can the universe stop? What exists on the other side, when the universe ends? It has to go on forever.” And this inner conversation continues, as he struggles to contemplate the infinite within his finite mind.
