Cultivating Compassion: The ‘Metta Garden’ as a Spiritual Practice for Ecological Healing and Human Well-being

Abstract

As the ecological crisis intensifies, with 45% of flowering plants facing extinction, innovative approaches integrating spiritual practice and environmental conservation are urgently needed. This paper examines the 'Metta Garden' concept developed in Sri Lanka, which synthesizes Buddhist principles of lovingkindness (metta) and interdependence (paṭicca samuppāda) with therapeutic horticulture and biodiversity conservation. Drawing on Plant Humanities methodology and Buddhist ecological philosophy, this study explores how contemplative gardening practices can address both environmental degradation and human well-being simultaneously. The Metta Garden approach employs poison-free cultivation methods, mindful gardening practices, and habitat creation for all beings, grounded in the Buddhist understanding of the four elements (water, fire, air, earth) and non-violence (ahimsa). The design incorporates walking meditation paths that engage all five senses while supporting progressive stages of spiritual development. Drawing on documented outcomes from a five-year case study of the Metta Garden, this paper synthesises existing research and practice evidence to examine how butterfly species recovered from 6 to 64, alongside thriving populations of native bees, birds, and soil organisms. Rather than presenting original empirical data, this article provides a critical review of the garden’s documented outcomes within a Plant Humanities and Buddhist ecological framework. The initiative has fostered significant community engagement through shared harvests, composting programs, and educational activities, creating networks of environmental stewardship and social healing. Therapeutic outcomes include enhanced mental health through stress reduction, increased mindfulness, and strengthened community connections. This research contributes to emerging scholarship in Plant Humanities by demonstrating how traditional Buddhist wisdom can inform contemporary conservation strategies. The Metta Garden model offers scalable applications for urban agriculture, climate resilience, and therapeutic horticulture programs globally, suggesting that integrating spiritual practices with ecological restoration creates pathways toward both environmental healing and human flourishing. The findings indicate that addressing the cultural and psychological dimensions of environmental crisis through contemplative practice may be essential for achieving lasting ecological transformation.
