In the quote from John O'Donohue's book "Walking in Wonder: Eternal Wisdom for a Modern World," he explores the relationship between fear and wonder. He suggests that fear can arise from a state of wonder that has turned inward, leading to a destructive cycle where curiosity and awe transform into anxiety and negativity. This shift detracts from the true essence of experiences and impacts one’s perception of the world.

O'Donohue contends that when wonder is overshadowed by fear, it loses its purity and potential for growth. Instead of exploring the richness of existence, fear confines individuals, limiting their ability to see the beauty and depth of life. This perspective invites readers to recognize the importance of maintaining a positive sense of wonder to counteract the negativity that fear can bring.
