Saint Swami Vivekananda, born as Narendra Nath Dutta, is one of the few peoples who introduced Indian philosophies of Vedanta and Yoga to the world. He is one of the main disciples of great saint of that time Ramakrishna Paramhansa. Swami Vivekanada later founded the institutions like Ramakrishna Math and Ramakrishna Mission. In a very short life he achieved something that will be hard to narrate even in thousand pages. This great man was born in reputed Datta family in Kolkata to Vishwanath Datta and Bhuvaneshwari Devi. His father was an attorney with interest in varying subjects.
From a very small age he had an earnest desire to know the god. He went to the various holy people to inquire the truth but he did not get the answer. He asked the very pragmatic question to the religious persons that whether they have seen the god. He found good mentors in Swami Ramkrishna who satiated his queries and gave him visions of God. It is in Ramakrishna guidance that Narendranath Datta transformed himself to a visionary and religious and spiritual leader. His guru also gave him vision for earth. The plight of Indian common men deeply affected him. He got an opportunity to speak for Hinduism at Chicago's Parliament of Religions in 1893. His oratory skills earned admiration for him and hind religion alike.
This great visionary passed on July 4, 1902.
After the death of Swami Ramakrishna, Swami Vivekananda visited different parts of India as a saint.
