PROUT stands for PROgressive UTilization Theory. It means, the progressive utilization and rational distribution of all the earth's natural resources. PROUT advocates another type of revolution called "nuclear revolution." In nuclear revolution, every aspect of collective life - social, economic, political, cultural, psychic and spiritual - is completely transformed. New moral and spiritual values arise in society which provide the impetus for accelerated social progress. The old era is replaced by a new era - one collective psychology is replaced by another. This type of revolution results in all-round development and social progress.
