If thou follow thy star, thou canst not fail of a glorious haven.

The line casts human life as a voyage guided by a personal “star”—a figure for one’s divinely appointed vocation, inner calling, or providential direction. To “follow thy star” implies fidelity to the highest form of guidance available to the self (conscience, grace, or destiny), rather than to shifting worldly aims. The “glorious haven” completes the nautical metaphor: perseverance in that true course leads not merely to safety but to a spiritually elevated end. In a Dantean frame, such imagery resonates with the poem’s larger movement from confusion toward ordered love and ultimate beatitude, where right orientation—toward the good—determines the soul’s arrival.
