I cannot reach it, and my striving eye
Dazzles at it, as at eternity.

The speaker describes an object of contemplation—spiritual truth, divine light, or ultimate reality—that remains beyond human grasp. The “striving eye” suggests earnest intellectual and devotional effort, yet the very act of looking produces “dazzle,” as when one stares into intense brightness. By likening the experience to looking “at eternity,” the lines frame the divine as simultaneously alluring and overwhelming: it draws the soul forward while exposing the limits of perception. The effect is characteristic of devotional poetry that treats God as both knowable through desire and unknowable in essence, turning frustration into reverent awe.
