The answer is: 5

Psalm 1:1-2 - The book of Psalms is divided into five sections, reflecting both the structure of the Torah and the poetic nature of Israel's worship. Each division concludes with a doxology, highlighting a pattern of praise that mirrors creation’s rhythm in Genesis, linking life and spirituality.

The five sections of the book of Psalms are much more than just a convenient way to organize poetic verses; they offer a beautiful reflection of the rhythmic cycle found in creation itself. This structure not only presents varied themes — from sorrow and confusion to thanksgiving and celebration — but also opens a unique opportunity for readers and worshippers to connect with life’s cadence.

Consider that the very first Psalm sets the stage by contrasting the righteous life with the wicked one. This establishes a foundational mindset that runs throughout these collections—a reminder that our life’s path is filled with choices that lead to differing outcomes. And just like the five books of the Torah, which serve as a guiding framework for life in Israelite tradition, the Psalms guide their users always toward direct engagement with the divine, unlocking a facet of spirituality centered on personal experience and communal worship.

Furthermore, each section winds down with a doxology, which isn't just a formal finish. It is an invitation to reflect and rejoice, echoing Genesis's call to embrace creation's beauty. These doxologies reinforce a constant thread of appreciation and praise, creating a true connection to the eternal and sustaining presence of the Spiritual. It beautifully unites what it means to love and serve — aligning human experience with the universe's harmonious flow. Talking about trivia, did you know some Psalms could easily dovetail into a choral piece with their rhythmic repetitions and calls for community prayer? Such a musical quality unfolds the entire book into something profoundly richer!
