Present research paper concentrates on Vivekananda's concept of management. The Indian traditions endow with a very rich of concepts and thoughts in the realm of personality development and leadership. These thoughts have been presented exclusively in the Vedas and Upanishads, which are the richest sources of understanding personality development and leadership in ancient Indian thoughts. The issues of self, soul, human nature, human existence, and human experience in terms of what they are, what they mean, how they are determined, their manifestation in the human being and their role in reconciling personality development form the core themes around which personality development can be understood according to the ancient philosophical tradition. Swami Vivekananda's concept of development of personality is very much influenced by this philosophical perception. Vivekananda's speeches and writings deal with various aspects of life which go beyond the barriers of caste and creed, colour and community, time and clime and having a universal appeal. Vivekananda believes that growth in human personality during recorded time has been social rather than biological; it has proceeded not by heritable variations in the species, but mostly by social, intellectual and moral innovation transmitted to individuals and generations by imitation, custom or education.
