Eternity by William Blake

Blake's "Eternity" is a brief yet impactful poem that presents a powerful idea: clinging too tightly to joy or love can destroy it, whereas letting it go freely allows it to remain with you forever. Imagine trying to catch a butterfly—once you grasp it, it's lost. Although it's one of Blake's shortest works, it encapsulates his entire philosophy on freedom, desire, and what happiness truly means.

The tone is assertive and aphoristic — Blake isn't posing questions; he's delivering a verdict. There's a subtle urgency to it, akin to advice from someone who has already learned the hard way. Despite tackling cosmic themes like eternity, the language remains personal and almost chatty, a hallmark of Blake at his most succinct.

Blake crafted this brief lyric during the Romantic period, a time when poets were actively resisting Enlightenment rationalism and the industrial mindset that reduced everything to mere utility and ownership. He was particularly focused on what he termed "mind-forged manacles"—the invisible chains people create for themselves and others through possessiveness, jealousy, and strict moral codes. "Eternity" fits right in with the aphorisms found in his *Notebook* and the *Proverbs of Hell* from *The Marriage of Heaven and Hell* (1790), where he contended that energy and desire are sacred rather than sinful. The poem embodies his lifelong belief that genuine spiritual life involves embracing experiences instead of hoarding or stifling them. It was likely penned in the 1790s, a decade marked by revolutions in France and America that made the concept of freedom feel both urgent and immediate.
