Wisława Szymborska's quote suggests that life offers valuable experiences without requiring a price. Dreams are accessible to everyone, allowing for creativity and exploration without any financial burden. On the other hand, losing one's illusions can be painful and costly, indicating that our perceptions and expectations shape our happiness.

The mention of the body having an "installment plan" implies that our physical existence comes with its own natural rhythms and processes. Instead of viewing life as an expense, the quote encourages us to appreciate the richness of our experiences and the inherent value of being alive.
