The couplet questions who would have allowed the experience of joy without pain, and then states the act of always gazing at stars even without the night.

This couplet is a profound meditation on the nature of intense experience. The poet questions how one can taste such a deep pleasure without enduring any pain or shock. It suggests that the beauty of life, or perhaps the intensity of love, is inextricably linked to suffering. Gazing at the stars 'without night' implies a constant, unending state of wonder—a state that is both glorious and overwhelming. It captures the exquisite agony of continuous emotion.
