Guru Har Kishan Sahib Ji was born on Sawan Vadi 10 (8th Sawan) Bikram Samvat 1713 (17 July 1656) at Kiratpur Sahib. He was the second son of Guru Har Rai Sahib Ji and Mata Kishan Kaur. Ram Rai Ji was the elder brother of Guru Harkishan Sahib Ji. Ram Rai ji was expelled from the Sikh Panth because of his anti-Guru Ghar activities and standing in favor of the Mughal Sultanate.

At the young age of 5, Guru Har Kishan Sahib was given the Guruship. Guru Har Rai Ji installed Guru Harkishan Ji as the eighth Guru in 1661. Angered in this way, Ram Rai ji complained about this to Aurangzeb . Taking the side of Ram Rai, Shah Jahan ordered Raja Jai ​​Singh to present Guru Har Kishan ji before him. Raja Jai ​​Singh sent his messenger to Kiratpur and ordered the Guru to be brought to Delhi. At first Guru Sahib expressed reluctance. But on the repeated requests of his Gursikhs and Raja Jai ​​Singh, he agreed to go to Delhi.

Once Raja Jaisingh presented many women, who were equally well-dressed, before Guru Sahib and asked them to identify the real queen. Guru Sahib went and sat on the lap of a lady who was dressed as a maid. This woman was the real queen. Apart from this, many sakhis are prevalent in Sikh history regarding his intellectual ability. Within a short span of time, Guru Har Kishan Sahib Ji gained popularity among the people in the capital by his friendly behavior with the general public. During this time, the outbreak of diseases like cholera and chhoti mata brought epidemics in Delhi. Mughal Raj was insensitive towards the public. Ignoring caste and high and low, Guru Sahib launched a campaign to serve all Indians. Especially the Muslims living in Delhi were very impressed by his service to humanity and they started calling him Bala Pir. Even Aurangzeb could not disturb him in view of public sentiment and circumstances. But at the same time, Aurangzeb kept Ram Rai ji instigated, so that social differences could be exposed.

While serving the people affected by the epidemic day and night, Guru Sahib himself also suffered from high fever. Chhoti Mata's sudden outburst tied him to the bed for several days. When his condition became more serious, he called his mother to him and said that his end was near. When he was asked to name his successor, he only took the name of 'Baba Bakala'. The term was applied only to the future Guru, Guru Tegh Bahadur Sahib, who was living in the village of Bakala on the banks of the Beas River in Punjab. In his last time, Guru Sahib instructed all the people that no one should cry on his death. Rather, we will sing the words written in Gurubani. In this way, on Bala Pir Chait Sudi 14 (3rd Vaisakh) Bikram Samvat 1721 (9 April 1664) softly reciting the word Waheguru merged into Jyotijot. Guru Gobind Sahib Ji while paying his respects recorded in Ardaas that Mr. Harkishan dhiiye, the one who hurts everyone.
