As a result of Sri Rama Krishna’s inspiration, Vivekananda adopted the Advaita school of thought, accepting the idea that only Brahman is real and everything else is false. Brahman that I am. Reality, according to Vivekananda, is one supreme Brahman. He emphasises the reality’s monastic nature. Vivekananda, a Neo-Vedantist, acknowledges Brahman as being beyond space, time, and causality. He saw that each person’s energy is a manifestation of divinity and created a very uplifting psychology of humanity. His achievement rests in using Advaita Vedanta’s social philosophy, which paved the way for social changes in India. Advaita Vedanta practice was promoted by him in aspects of society-related everyday living. He used Advaita Vedanta philosophy to create a more spiritual and humane world. Everything revealed his realistic Vedanta idealism.
