In Alexander McCall Smith's "Precious and Grace," a conversation unfolds between the characters Precious and Mr. J.L.B. Matekoni regarding the nature of the soul as one ages. She inquires whether he believes our souls expand over time, prompting a moment of reflection before he responds. His thoughtful answer likens the growth of the soul to the outward stretching of tree branches, suggesting a natural and beautiful development.

This metaphor highlights the idea that as people experience life, their souls become richer and more inclusive, expanding their capacity for love, understanding, and connection. It reflects a profound understanding of personal growth, emphasizing that life experiences contribute to a deeper sense of self and a wider perspective on the world around us.
