The quote reflects the idea that the characters in "Meridian" by Alice Walker possess a hidden, profound understanding of their existence. They are aware of their own mortality and the implications that come with it. This awareness creates an inner life that is both rich and complex, as they navigate their roles as parents and the burdens of life despite being aware that they are essentially beyond it.

This secret joy mentioned in the quote suggests that their motivation to continue living stems from their love for their children. It highlights the tension between life and death, as they experience a kind of joy not in living for themselves but in the hope and future of their offspring. Their existence is stripped down to its essence, embodying a poignant sacrifice as they maintain their lives for the sake of the next generation.
