The Mahanubhava tradition of Maharashtra represents an unbroken system of living heritage where devotion, ecology, manuscript culture, and architecture form a seamless whole. Originating in the twelfth century under Shri Chakradhar Swami, this movement crystallised into a rigorous philosophical and social order that linked spiritual realisation with community practice. This chapter reinterprets the tradition as a dynamic heritage system—a web of relationships between manuscripts, temples, festivals, ecological ethics, and collective custodianship. Drawing upon archival, ethnographic, and digital evidence, it explores how the Mahanubhava ethos sustains itself across centuries through self-regulating mechanisms: textual preservation, ascetic discipline, ritual ecology, and community participation. The chapter also traces new trajectories of conservation in the digital era, where online archives and digitisation projects extend the living pulse of the tradition into the global domain. Through this case study, it argues that the Mahanubhava system exemplifies an indigenous model of sustainability, rooted not in nostalgia but in adaptive continuity.
