His promotion of Hinduism started with his keynote address at the world Parliament of Religious meeting in Chicago. He also advocated the idea of harmony of religions based on his experience that all religions lead to the realisation of the same reality. It won accolades and people were mesmerised by the speaker and his message. In his last days he gave Vivekananda the responsibility of looking after the disciples and running the mission. He left for his heavenly abode on August 16, 1886 and till the last moment the name of his Goddess was on his lips.
