During the middle of 1885, Ramakrishna, who had been suffering from throat cancer, fell seriously ill. In September 1885, Sri Ramakrishna was moved to Shyampukur in Culcutta, and a few months later Narendranath (Swami Vivekanand) took a rented villa at Cossipore. Here, he formed a group of young people who were ardent followers of Sri Ramakrishna and together they nursed their Guru with devoted care. On 16 August 1886, Sri Ramakrishna gave up his mortal body.
After the demise of Sri Ramakrishna, around fifteen of his disciples including Narendranath began to live together in a dilapidated building at Baranagar in North Calcutta, which was named Ramakrishna Math, the monastic order of Ramakrishna. Here, in 1887, they formally renounced all ties to the world and took vows of monkhood. The brotherhood rechristened themselves and Narendranath emerged as Vivekananda meaning "the bliss of discerning wisdom".
The brotherhood lived off on alms donated voluntarily by patrons during holy begging or ‘madhukari’, performed yoga and meditation. Vivekananda left the Math in 1886 and went on a tour of India on foot as a ‘Parivrajak’. He travelled the breadth of the country, absorbing much of the social, cultural and religious aspects of the people he came in contact with. He witnessed the adversities of life that the common people faced, their ailments, and vowed to dedicate his life to bring relief to these suffering.
