Deity and Spirit Possession in South Asia is an academic study that examines traditions of deity and spirit possession across the diverse religious and cultural landscapes of South Asia. Drawing on anthropology, history, sociology, and religious studies, the book explores how possession practices are understood and experienced in different communities, including Hindu, Buddhist, Muslim, tribal, and folk traditions. Through ethnographic research and historical analysis, it examines the social, ritual, cultural, and symbolic roles of spirit possession, healing ceremonies, religious devotion, and community identity. Rather than promoting or validating supernatural claims, the book presents these practices as subjects of scholarly inquiry, offering valuable insight into the beliefs, rituals, and lived experiences of South Asian societies.
