This article explores the conceptual field of afterlife in English and Uzbek languages from the perspective of cognitive linguistics. It focuses on the semantic, metaphorical, and cultural aspects of the concept, which reflect the two nations’ spiritual and moral worldviews. The afterlife concept is analyzed through religious texts, idiomatic expressions, proverbs, and literary works to determine its cognitive structure and metaphorical models. The study shows that in both linguistic systems, the concept of afterlife is linked with moral accountability, dualistic opposition (heaven/hell, jannat/do‘zax), and the eternal destiny of the soul. However, while English discourse emphasizes peace, personal salvation, and eternal rest, the Uzbek worldview highlights divine justice, responsibility, and moral duty.
