India’s natural water bodies—rivers, lakes, ponds, and springs—have long been revered as sacred entities in Hinduism, Buddhism, Jainism, and Sikhism. This chapter looks at the interrelationship between religion and ecology and the cultural practices surrounding water bodies in India. It examines the rituals, ceremonies, and beliefs associated with water bodies in India, acknowledging their dual function in maintaining both ecosystems and spiritual health. It considers the threats to these sacred bodies of water and the proactive steps taken to protect or conserve the water for present generations and future posterity. These include: community-based conservation efforts; co-management arrangements with bureaucratic authorities; and policies influencing people to adopt sustainable and environmentally friendly approaches to aquatic water bodies. The hope is that, despite the broader culture of indifference towards the environment, a more pronounced awareness of cherished sacred waters can raise their spiritual and ecological value to the extent that future generations treat them appropriately. The contributions within the chapter demonstrate how religious and ecological ideas have enabled worship and conservation as cultural, religious practices, as well as how current-day issues (pollution, overuse, unethical harvesting) threaten this relationship. It returns to previous spiritual texts, ethnographical materials, and environmental policies to provide evidence that religious traditions can support water sustainability. The chapter refers to, and makes the case for, greater collaboration across interests with religious leaders, relevant bureaucracy, and communities to support sustainability-oriented water management practices. By recognising the interconnectedness of spiritual beliefs and environmental stewardship, there is potential for significant progress in protecting our precious water resources.
