Guru Har Krishan is the eighth Master in Sikh Dharma. He became Guru at the age of five and breathed his last at the age of 8 in New Delhi, India, where the Gurudwara of Bangala Sahib has been established. He was born at Kiratpur, India. His father was Guru Har Rai and his mother was Mata Kishan Kaur.
When the Guruship passed to a young child of 5, there were some in the community who could not believe that a little boy could lead them. One such person, Lal Chand, challenged Guru Har Krishan to debate the meaning of scripture. In response, Guru Har Krishan requested that Lal Chand go and find someone to speak on the Guru's behalf. Lal Chand searched the town and brought a deaf, mute and illiterate water-carrier, Chhaju Ram, to speak on the Guru's behalf. Guru Har Krishan touched the head of the water carrier with his shoe. Suddenly Chhaju Ram became awakened - and proceeded to give a simple but profoundly moving discourse on the meaning of scripture. Lal Chand begged for forgiveness from Guru Har Kirshan and the community fully accepted the child's ability to lead the community.
There was an epidemic of small pox in Delhi. Guru Har Krishan went to the place where the outbreak had occurred and through his blessing, a spring of sacred water appeared that could heal the people of the illness. He took on the suffering and sickness of the area, taking on the small pox himself - giving his life to help save the lives of others.
