The quote from João Guimarães Rosa's "Grande Sertão: Veredas" reflects on the complexity of human existence and our shared mental landscape. It suggests that the challenges and thoughts that occupy our minds are vast and overwhelming, leading us to question the sanity of those around us. Rosa portrays the struggle of individuals as they confront the enormity of their thoughts and experiences in a world that often feels chaotic.

This introspection emphasizes the need for personal growth and expanded understanding amid a bustling reality. The idea of "increasing our heads" implies that we must strive to broaden our perspectives and deepen our comprehension of life, acknowledging that our collective consciousness is shaped by countless factors. Ultimately, Rosa invites readers to reflect on the nature of sanity and the human experience within an intricate and often confounding world.
