In his work "The Archetypes and the Collective Unconscious," C.G. Jung emphasizes the vital role of the human spirit. He suggests that without the dynamic energy of the soul, individuals risk stagnation and decay in their lives, particularly in their most pressing urge: inactivity. This idea highlights the importance of passion and movement in one's existence.

Jung's quote reflects a deep psychological insight, pointing to the necessity of engagement and vitality. The "leaping and twinkling" of the soul represents the spark that drives people to pursue their passions and avoid the torpor of a stagnant life. He proposes that embracing this inner vitality is essential for personal growth and fulfillment.
