On July 4, 1902 at Belur Math near Calcutta, he taught Vedanta philosophy to some pupils in the morning. He had a walk with Swami Premananda, a brother-disciple and gave him instructions concerning the future of the Ramakrishna Math. Vivekananda died suddenly later that day. He had predicted that he would die before the age of 40, which proved to be true when he died at the age of 39.
