Swami Vivekananda, one of India's most revered spiritual leaders, was born in Kolkata on January 12, 1863, as Narendra Nath Datta. Vivekananda renounced the worldly pleasures in 1887 along with other disciples of Ramakrishna Paramhansa and took formal vows of sannyasa. The spiritual leader's iconic speech at the World's Parliament of Religions in Chicago in 1893, is still remembered today. Vivekananda had a special interest in Western philosophy and history and was often assailed by doubts about the existence of God. Through his speeches and lectures, he tried to awaken the religious consciousness among people and also tried to uplift the downtrodden using the principles of practical Vedanta.
