This paper examines the Brahma Kumari tradition and its role in socio-cultural transformations in India and beyond. The focus is on the issue of spiritual identity, meditation, service to society and female leadership. I examine several aspects of the implication of Brahma Kumaris in service to society and their contribution to the uplifting of women and untouchables, and to the creation of a new awareness of climate change. I will focus on socio-cultural transformations leading to female empowerment, the transformations of slums into "divya nagar", or divine cities, and environmental improvements. What is the role of spirituality and meditation as a driving force for these positive socio-cultural changes in individuals and in society? Can the belief that change starts from within make a lasting impact on society? Are there any other socio-cultural transformations that happen in this way? By means of analysis of texts and data from interviews with Brahma Kumari followers, this paper discusses the important societal impact of the Brahma Kumari tradition and its contribution to meaningful socio-cultural transformations.
