Song Meaning
This sonnet opens with a direct address, a sharp rebuke to the "poor soul" at the "centre of my sinful earth." The narrator questions why this soul would "pine within and suffer dearth," decorating its "outward walls so costly gay" when its existence is so fleeting, on a "short lease." It's a stark contrast between the ephemeral beauty of the physical body and the inner suffering of the soul.
The central tension lies in the perceived misallocation of resources and focus. The narrator argues that the soul is squandering its limited time and energy on the "fading mansion" of the body, only for it to be consumed by "worms." This excess spent on the physical is ultimately futile, leading to a profound sense of loss and decay.
The most striking craft element is the radical reorientation proposed in the latter half. The narrator urges the soul to "live thou upon thy servant's loss," essentially suggesting that the soul should thrive by letting the body diminish. This is achieved by "selling hours of dross"—mundane, physical time—to "buy terms divine," a spiritual investment that promises eternal life. The physical is devalued, while the spiritual is elevated to an ultimate currency.
This redefinition of value is what makes the sonnet so potent. It flips the conventional understanding of life and death, wealth and poverty. By framing spiritual gain as a consequence of physical decay, the poem offers a powerful, albeit paradoxical, path to overcoming mortality. The final couplet, "So shall thou feed on Death, that feeds on men / And Death once dead, there's no more dying then," presents a triumphant, almost defiant, vision of spiritual immortality achieved through this profound internal shift.
