This contribution explores the transformative potential of Interreligious Dialogue (IRD) across cultures, drawing from the author's experiences in Kenya and Sri Lanka. Through examining these contexts, shared principles will be formulated to offer practical guidelines for IRD work in diverse settings. The discussion focuses on two key actors: the Institute for Interreligious Dialogue and Islamic Studies (IRDIS) at Tangaza University, Nairobi, and the Centre for Society and Religion (CSR), Colombo. While each has unique contributions, their approaches provide valuable lessons, best practices, and insights into areas of contention across religious, historical, and cultural diversity. IRD holds significant promise in highly religious yet fragmented societies like Kenya and Sri Lanka. It acts as a safeguard against manipulative narratives, blame games, and "us versus them" ideologies. By demystifying "the other," IRD creates inclusive spaces for dialogue, particularly empowering women, youth, and minorities while respecting their identities as people of faith. Beyond bridging interreligious tensions, IRD addresses identity-based conflicts, especially in ethnically divided societies where religion often intersects with these disputes. Effective peacebuilding requires integrating religion to unpack root causes—social, ethnic, or economic—and both IRDIS and CSR actively engage in this process within their unique contexts. Religious institutions play crucial roles where governments fail to meet social and economic needs, fostering disillusionment with political systems. IRD provides platforms for advocating shared goals, such as responses to the COVID-19 pandemic, demonstrating the effectiveness of community-based approaches when linked to broader issues like social justice, gender, and environmental concerns. This contribution highlights strategies from IRDIS and CSR to formulate culturally sensitive recommendations for replicating successful IRD practices elsewhere.
