In George Eliot's "Daniel Deronda," the idea of passion is likened to a seed that grows and flourishes from within. This metaphor suggests that passion is not just an external influence but something innate that requires nurturing to develop fully. As it grows, passion becomes a central force in one’s life, shaping thoughts, actions, and decisions.

This portrayal emphasizes that passion can dominate one's existence, directing all aspects of life towards its fulfillment. Just as a seed leads to a plant that influences its surroundings, passion can dictate life’s direction and priorities, making everything else secondary to its ultimate goal.
