Sri Guru Granth Sahib Ji was first compiled by Sri Guru Arjan Dev Sahib Ji at Amritsar between 1600-1604, Guru Ji narrated the Gurbani and Bhai Gurdas Sahib Ji was the scribe. Guru Sahib had collected the works of the previous Gurus and then added works from other saints and their own utterances of Gurbani. Sri Guru Granth Sahib Ji was first installed at Harimandar Sahib (Golden Temple, Amritsar) on the 16th of August 1604 with Baba Buddha Sahib Ji being the first Granthi.
Gobind Rai spent the first five years of his life in Patna. As a child, he used to play war games with other children, leading mock battles. He had many admirers, including a learned Brahmin called Pandit Shiv Dutt (or Shiv Das). Once, Raja Fateh Chand of Patna and his Rani, a childless couple, visited Shiv Dutt, and asked him to bless them with a child. Shiv Dutt suggested that if an innocent child like Gobind Rai prayed to God, their desire would be fulfilled. The couple then asked young Gobind Rai to visit their palace, where the Rani asked Gobind Rai to pray to God to bless her with a son like him. Gobind Rai smiled and said that there can be nobody like him, so the Rani should call him her son. From that day, the Rani started calling him Bala Pritam ("child God"). The royal couple allowed Gobind Rai and his friends to freely play in their palace, and also built a big dining hall for the children.
Shortly after the birth of Guru Teg Bahadur, Sri Guru Har Gobind Sahib asked many priests, including Baba Budha Ji and Baba Gurdas to come with him and bless the child. On seeing the child, Guru Har Gobind and Baba Budha bowed to the him and touched his feet. On being asked by one of his followers to explain his actions, Guru Har Gobind said that Guru Teg Bahadur was sent to this world with a great mission: he would sacrifice his own life for the welfare of others. Sri Guru Har Gobind Sahib always wore two swords; Miri (political sovereignty) and Piri (spiritual sovereignty). When Guru Har Gobind Sahib picked up his child, Guru Tegh Bahadur picked up the sword that represented Piri.
Guru Har Krishan was born in Rupnagar, Punjab, India to Guru Har Rai and Kishan Kaur (Mata Sulakhni). Before his death in October 1661, Har Rai designated his younger son Har Krishan as the next Guru. Har Rai chose Har Krishan, rather than his elder son Ram Rai, because Ram Rai was in collusion with the Mughal Empire. Har Krishan was only five years old when he succeeded his father as Guru.
Although, Guru Har Rai Ji was a man of peace, he never disbanded the armed Sikh Warriors (Saint Soldiers), who earlier were maintained by his grandfather, Guru Hargobind. He always boosted the military spirit of the Sikhs, but he never himself indulged in any direct political and armed controversy with the contemporary Mughal Empire. Once on the request of Dara Shikoh (the eldest son of emperor Shahjahan), Guru Sahib helped him to escape safely from the bloody hands of Aurangzebs armed forces during the war of succession.
