[Display omitted] • The paper shows how spirituality strategically supports an Adivasi self-empowerment movement in India. • Spirituality provides motivation, makes groups' indigeneity visible, and protects their activities against reprisals. • Tribal groups in India using this strategy can escape debt bondage and gain their own land. • Action organisations working with subaltern groups can orchestrate spirituality to achieve progressive goals. Spirituality strategically enables self-empowerment in a clandestine movement of Adivasis which this paper calls 'the Programme'. To explain how social movements and action organisations can orchestrate spirituality, this paper examines how the Programme helps landless rural people overcome debt bondage and gain land by employing spiritual repertoires. The paper addresses the question how, in the context of an increasingly tribalised politics in India, spiritual orchestration allows some Scheduled Tribes to make substantive economic gains, especially on debt freedom and land rights. The paper draws on an analysis of qualitative data collected through workshops, interviews and visits to villages across several Indian states, which has been anonymised to protect identities and avoid divulging sensitive information. The study finds that spirituality supports self-empowerment in three ways: first, it provides motivation and ideological reinforcement for people engaging in struggles against debt bondage and for land rights; second, it makes tribal identity more visible and helps groups make claims as indigenous owners; third, it offers groups protection from reprisals and creates platforms for engaging powerful actors. These findings are significant because, for activists and scholars who work with subaltern groups in India or other contexts, they demonstrate that the orchestration of spirituality can strengthen action repertoires for self-empowerment and help groups secure or protect economic and social gains. The paper adds insights to research on social movements and organisations on how to strengthen the 'weapons of the weak'; it contributes empirical knowledge about how strategies to overcome debt and exploitation can succeed; and it underscores the importance of protecting freedom of religion and belief in development practice.
