This quote invites reflections on perception, existence, and the natural boundaries between life and death. It challenges the conventional understanding of the sky and earth by suggesting an imaginative reversal—where the sky might be a vast sea of fresh water, and we are not walking under it but on top of it. The imagery compels us to reconsider our place in the universe and the way we process reality. It suggests a fluidity between earth and sky, life and afterlife, and even vision itself.

The idea that "perhaps we see everything upside down" pushes us to contemplate perspective—the lenses through which we interpret the world. Much like the phenomenon where an image is inverted on the retina and the brain corrects it, what if our entire lived experience is, in essence, turned on its head? This challenges the ego’s confidence that its understanding of reality is the ultimate truth.

Additionally, the reflection on death as sinking into the sky elegantly combines elements of mystery and acceptance. Rather than seeing death as an end, the metaphor of falling into the sky suggests a return to a larger, encompassing entity—perhaps a cycle rather than cessation. It subtly touches on themes of transformation and the continuity of existence beyond physical life.

Overall, the quote arouses a meditative mood rich in philosophical wonder. It underscores the power of metaphor to transcend literal reality and encourages us to embrace ambiguity, fluid identity, and the unknown. The poetic expression resonates with the themes often explored in José Luís Peixoto's work: the interplay of life, death, nature, and existential inquiry.
