Monique Cissay explores how the letters of a person's first name can influence their life path, offering a practical guide to applying numerology in everyday situations. Drawing on traditional numerological principles, the book explains how to calculate the numerical value of a name, interpret its significance, and make adjustments—such as choosing an alternative spelling or nickname—to align with desired outcomes. Readers are provided with step‑by‑step exercises, case studies, and tips for integrating these insights into career decisions, relationships, and personal goals. While rooted in French cultural contexts, the concepts are presented in a clear, accessible style that invites anyone curious about the symbolic power of names to experiment with this ancient practice.
