In Lighter, Yung Pueblo (Diego Perez) offers not a theoretical treatise, but a guide to healing forged in the crucible of profound personal experience. His credibility stems from a transformative journey that began at a "rock bottom" of drug abuse—a painful deviation from his past as a youth activist and the selfless sacrifices of his immigrant parents. Through radical honesty and meditation, Perez navigated his way back to his purpose. The book's central thesis is the inextricable link between personal and global transformation. Pueblo argues this path is a deliberate shedding of conditioned human habit—reactive patterns rooted in fear—to reclaim our authentic human nature, a state of innate clarity and love.

Lighter demystifies this process for seekers weighed down by suffering, compellingly exploring how to make healing an actionable practice, the link between self-love and emotional maturity, and how individual change ripples outward to create a more compassionate world. It is a hopeful and practical manual for becoming not just lighter, but freer.
