John O'Donohue emphasizes the importance of balance in his work "Eternal Echoes: Celtic Reflections on Our Yearning to Belong." He argues that functionalism, when viewed in isolation, can be detrimental, as it reduces life to mere utility. Without a complementary sense of reverence, people's experiences become devoid of depth and significance. This lack of appreciation can lead to a disconnected existence.

The notion of reverence infuses life with a sense of presence and wonder, enriching human experiences and fostering genuine connections. O'Donohue highlights that acknowledging beauty and mystery is essential for a fulfilling life. Through reverence, individuals can cultivate a deeper understanding and appreciation for their surroundings and relationships, ensuring that functional aspects of life do not overshadow the more profound, spiritual elements of existence.
