This study examines how Rabindranath Tagore’s Gitanjali develops a sustained system of imagery that resonates with the non-dual philosophical orientation of Advaita Vedānta. Through close readings of selected poems, the article analyses how sensory metaphors ranging from images of divine immanence and the surrender of the limited self to representations of silence as an inner contemplative space and the flowing continuity of life collectively gesture toward a vision of underlying unity beneath the diversity of the phenomenal world. Recent scholarship that situates Tagore alongside Advaita-oriented thinkers such as Vivekananda and Ramana Maharshi (Kumar & Annapurna, 2025), along with earlier critical accounts that perceived non-dual undertones in Gitanjali’s initial global reception (Ananthan, 2018), reinforces the plausibility of reading the text within a non-dual framework. Rather than collapsing Tagore’s devotional lyricism into strict philosophical discourse, this study foregrounds imagery as the medium through which the poet aesthetically performs Advaita’s central insights, revealing a poetic grammar that intertwines mystical experience with metaphysical intuition.
