In "The Dragon Reborn" by Robert Jordan, the quote "The way back will come but once. Be steadfast" underscores the importance of perseverance and the singularity of certain opportunities in life. It suggests that some moments or paths will only present themselves a single time, making it crucial to remain resolute in one's decisions and actions.
The message encourages individuals to seize their chances and to stay determined, as they may not encounter the same opportunity again. This theme resonates throughout the narrative, emphasizing the need for courage and commitment in the face of challenges and uncertainties.
