Swami Vivekananda was a Hindu monk born in 1863 in Calcutta, India. He founded the Ramakrishna Mission and Ramakrishna Math. Vivekananda believed that religion should be at the core of education and advocated for religious texts like the Gita, Upanishads, and Vedas to be part of the curriculum. He saw religion not just as theory but as a practical necessity for developing character, mental strength, and self-realization. Vivekananda's principles of education emphasized developing the character, physical abilities, intelligence, and spirituality of students in order to build a self-confident and self-reliant nation.
