Guru Harkrishan Ji was the youngest son of Guru Har Rai Ji.  His mother’s name was Kishan Kaur.  Guru Harkrishan was called upon to assume the responsibilities of leadership of the Sikh community at the age of five.  Like the other founders, (Guru Nanak) Guru Harkrishan also was absorbed in meditation from early childhood, and was treated by the Sikhs with great affection and esteem.

Guru Harkrishan was a genius and showed extraordinary talents for his age.  Once Aurangzeb sent for Guru Harkrishan to appear in his court, where his elder brother Ram Rai appealed for his right to Guruship.

         On the way to Delhi, Guru Sahib Ji stayed at Ambala, where a proud  Brahmin, Pandit Lal Chand, Questioned him about the meaning of certain difficult passages in the Gita.  The Pandit wanted to test the intellectual powers of the Guru.  Guru Harkrishan asked the Pandit whether he should translate Gita himself or he should get it done from Chhajju Gunga.  The Pandit was happy to hear that Chhajju is going to translate the Gita, because Chhajju was a dumb person in the village.

                Guru Harkrishan put his stick on Chhajju and asked him to answer the Pandit’s questions.  Chhajju Gunga answered all the questions of the Pandit without any difficulty.  The Pandit felt ashamed and humbled; he fell on the feet of Guru Harkrishan Ji and begged for forgiveness

              In response to the wishes of the Sangat, Guru Harkrishan Ji went to Delhi with his Grandmother.  They stayed at a bunglo of Raja Jai Singh.  A beautiful Gurdwara (Bungla-Sahib) now stands to the Guru Harkrishan Ji’s scared memory.

                During Guru Harkrishan Sahib’s stay in Delhi, cholera broke out.  Guru brought health and happiness to much cholera stricken people.  Soon after Guru Harkrishan Ji fell ill.  The Sikh started to worry about his successor.  They asked the Guru who would guide them after.  Before taking their last breath Guru Harkrishan Ji pointed to his followers that the next Guru would be Baba Bakala.

                Guru Harkrishan Sahib Ji passed away March 30th 1664.
