Identify one common theme across many world religions.

The quest for meaning and understanding of existence is a central theme across many world religions. This theme reflects humanity's deep-seated need to comprehend life, its purpose, and the nature of the universe. Various religious traditions grapple with existential questions like: What is the meaning of life? Is there a higher power? What happens after death? These inquiries often lead followers to explore beliefs about creation, the divine, moral frameworks, and the nature of human existence.

In many religions, this quest manifests through rituals, teachings, and philosophical inquiries that aim to provide answers or at least guidance on life's most profound mysteries. For instance, Buddhism explores the nature of suffering and the path to enlightenment, while Christianity delves into the relationship between God and humanity, focusing on love and redemption. Similarly, Hinduism raises questions about the self and its relationship to the divine.

In contrast, the other options lack the broader existential focus that is characteristic of many spiritual traditions. Rejecting all forms of morality, pursuing material wealth, or consolidating political power do not address the fundamental human yearning for meaning and understanding that drives individuals towards spirituality and religious beliefs. Therefore, the quest for meaning stands out as a unifying theme in the exploration of world religions.
