Let me ask you a simple question with a complex answer: Are human beings only biological machines? Or is there something more to us, something that transcends mere flesh and blood?
Questions like that have challenged humanity for centuries, partly because we like to explain our world in clear-cut terms. We like things to be either all black or all white. No gray. But human life can’t be defined so easily. Each of us has a physical body, but we have a spiritual side as well.
