The song "If Rah" by Underworld features abstract and somewhat cryptic lyrics, making it open to interpretation. It seems to touch on themes of introspection, existentialism, and the complexities of human emotions. The lyrics convey a sense of searching for deeper meaning and understanding in life. The repetition of "Luna" throughout the song may reference the moon, which often symbolizes mystery, emotions, and reflection. It could suggest a desire to find clarity and illumination amid the struggles and challenges of existence. The line "The origin of numbers is a questionable hypothesis" implies a contemplation of the fundamental concepts that shape our understanding of the world and the uncertainty surrounding them. The mention of tattoos, beads of prayer, and shoes of stars could be symbolic images reflecting personal experiences, spirituality, and aspirations. References to a "white van," "Valhalla," and a "shimmer" are more mysterious and open to interpretation. They could be metaphors for different stages of life or moments of transcendence. Overall, the song appears to explore the complexities and contradictions of life and human experiences. It invites listeners to reflect on their own journeys and interpretations of existence.
