Guru Harikrishan ji was invited by Mughal King Aurengzed, but Guru ji refused to meet the Mughal King, and show any occult miracles of the type his ( Guru ji's ) brother Ram Rai, had shown in the Mughal court. During this era smallpox and cholera had broken in Delhi and Guru Harikrishan ji moved freely among the victims of the epidemic. Both Hindu and Muslims of Delhi were deeply moved by his compassion and human touch. Guru Harikrishan ji everyday distributed sanctified water to the sick and the poor, which had a miraculous healing effect on their mind and soul. To this day water sanctified by the word of God, sung all the day in the temple is distributed to those seeking their peace of mind. Raja Jai Singh dedicated his palace to the sacred memory of the Guru and since his death it has been the place of worship of the sikhs. Guru Harikrishan ji died of smallpox on March 30, 1664.
