The book defines and describes the relationships between Chopin's music and one of the oldest but still used monastic rules, the Rule of Saint Benedict. Its goal is to construct bridges between music and spirituality. Since these two realms both refer to human life, the chapters of the book deal with current and existential issues such as beginnings, authority, weakness, interactions, emotions and others. The Rule of Saint Benedict and Chopin's music appear to belong to the same stylistic category of human culture, characterized by nobleness, moderation and high sensibility. In this way two seemingly incompatible realities reveal their affinity to each other, and the one may explain the other. The book is situated at the boundary of musicology and theology. Its discourse is illustrated by many examples, carefully chosen from Chopin's music.
