<p>The purpose of the study is to explore the human-nature relationship entrenched inherently in the socio-cultural and ecological lifeworld of Keralam’s sacred groves (<i>Kavu</i>). The study aims to evaluate how a harmonious human-nature relationship is intrinsically based on the synthesis of biocentric and eco-centric sacred ecology within the Kavu. Employing ethnography, data is collected through participant observation, oral narratives, and unstructured interviews across four sacred groves: <i>Mannarasala</i>,<i> Iringole Kavu</i>,<i> Neeliyar Kottam</i>, and <i>Kammadam</i>. The analytical framework is founded on Clifford Geertz’s ‘Thick Description’ to contextually interpret the symbolic practices, ritual performances, and socio-ecological interactions in the sacred groves. The findings of the study reveal four interrelated dimensions of the synthesis of biocentrism and eco-centrism within the sacred groves: (a) The Matriarch and the Serpents (<i>Mannarasala)</i>, (b) incarnation of Goddess in <i>Kavu</i>, (c) Divine protection of Subaltern in <i>Neeliyar Kottam</i>, and (d) Performance as Conservation (<i>Kammadam</i>). Sacred groves maintain a synthesis of biocentric and ecocentric ethics and values embedded in the socio-cultural and religious life of the communities living within the Kavu.</p>
