Swami Vivekananda (Bengali: স্বামী বিবেকানন্দ, Shami Bibekānondo (help·info); Hindi: स्वामी विवेकानन्द) (12 January 1863 – 4 July 1902), born Narendranath Dutta (Bengali: নরেন্দ্রনাথ দত্ত, Hindi: नरेन्द्रनाथ दत्त ), was the chief disciple of the 19th century mystic Ramakrishna Paramahansa and the founder of the Ramakrishna Math and the Ramakrishna Mission. He is considered a key figure in the introduction of Hindu philosophies of Vedanta and Yoga to the “Western” World, mainly in America and Europe and is also credited with raising interfaith awareness, bringing Hinduism to the status of a major world religion during the end of the 19th century C.E. Vivekananda is considered to be a major force in the revival of Hinduism in modern India. He is perhaps best known for his inspiring speech beginning with “Sisters and Brothers of America”, through which he introduced Hinduism at the Parliament of the World’s Religions at Chicago in 1893.
Swami Vivekananda was born in an aristocratic Bengali family of Calcutta on January 12, 1863. Swami’s parents influenced his thinking—the father by his rational mind and the mother by her religious temperament. From his childhood, he showed inclination towards spirituality and God realization. As a guru, Ramakrishna taught him Advaita Vedanta (non-dualism) and that all religions are true, and service to man was the most effective worship of God. After the death of his Guru, Vivekananda became a wandering monk, touring the Indian subcontinent and getting first-hand knowledge of India’s condition. He later sailed to Chicago and represented India as a delegate in the 1893 Parliament of World Religions. He conducted hundreds of public and private lectures and classes, disseminating Vedanta and Yoga in America, England and a few other countries in Europe,china(Guangzhou in Guangdong province).
