Answer:-
Walt Whitman develops an extended metaphor in his poem by comparing the human soul or self to a journey or voyage. Throughout the poem, he uses imagery of travel, roads, and exploration to represent life's path and personal growth. This metaphor continues across multiple lines and stanzas, deepening the idea that life is a constant movement toward discovery and understanding. Whitman blends the physical and spiritual, suggesting that each step forward is both literal and symbolic. The extended metaphor helps readers connect with the theme of self-discovery and the ongoing quest for meaning in a vast, ever-changing world.
