metaphysical significance and transcultural impact of the sacred cosmic sound 'om' (ॐ) in hinduism and beyond: a comprehensive analysis

The sacred cosmic sound "Om" (or " ॐ ") is one of the most profound and universally recognized symbols in Hinduism, embodying the essence of the universe and ultimate reality (Brahman). This research explores the origins, metaphysical significance, and contemporary relevance of Om within Hinduism, as well as its influence in other religious traditions and modern spiritual practices. The study is rooted in an analysis of primary Hindu scriptures, including The Vedas, Upanishads, Bhagavad Gita, and Puranas, supplemented by secondary scholarly interpretations. The findings reveal that Om serves as the primordial sound from which the universe originates, as well as a central symbol in Hindu philosophy, representing the infinite, self-realization, and the connection between the finite and the infinite. The fourfold structure of Om, as detailed in the Mandukya Upanishad, is explored in relation to different states of consciousness—waking, dreaming, deep sleep, and transcendence—highlighting its integral role in meditation and spiritual practices aimed at achieving moksha (liberation). Furthermore, the study examines the adoption of Om in Buddhism, Jainism, and global spiritual traditions, underscoring its transcultural resonance and contemporary relevance in practices such as yoga and mindfulness. The research also addresses the gap between the ancient spiritual interpretations of Om and its modern applications, suggesting that a deeper understanding of its metaphysical and scriptural roots can enrich contemporary spiritual practices. This study contributes to both academic and interfaith dialogues, offering a comprehensive analysis of Om’s profound significance across religious and philosophical contexts.
