7. Har Rai, 1644 – 1661, 17 years as Guru
He was the grandson of Guru Hargobind. Known to be a very compassionate and kind person, he was concerned not only about the welfare of human beings, but also that of the animals. In fact he was so soft hearted that he even helped to heal the son of Shah Jahan from an almost fatal illness despite the hostility the Mughals had shown to the guru’s predecessors.

He was the son of Guru Har Rai. He became Guru when he was only 5 years old. He died at the age of 8. He died of smallpox. His last words were “Baba Bakala”. The next Guru would be from the village of Bakala which was the case.
9. Tegh Bahadur, 1665 – 1675, 10 years as Guru
Tegh Bahadur means “hero of the sword”. He was the son of Guru Hargobind. He founded the Sikh centre of Anandpur. He was also a poet and composed over 50 hymns. He became a martyr in order to protect religious freedom. He was tortured and beheaded in Delhi by the Mughals.
10. Gobind Singh, 1675 – 1708, 33 years as Guru
He became the Guru in 1675 AD at Anandpur Sahib at the age of 10 years 11 months. He was the son of Guru Tegh Bahadur and was known for his leadership, bravery, and personal sacrifices. He initiated the Five K’s of the Khalsa that define Sikhs to date. The Dasam Granth is a collection of poems written by Gobind Singh. Bulleh Shah hailed him as the ‘protector’ of religious freedom and said “Had Gobind Singh not been there, They would all be under Islamic sway.” He was called "Sarbans Dani" because of the supreme personal sacrifices he made.
11. Shri Guru Granth Sahib (SGGS), 1708 – Forever
The SGGS is often described as the “Parliament of Religions”, a model for interfaith harmony. It is the only religious script in the world that contains views and ideology of people of other religions, caste and creed.
Guru’s light (Jote) lives in the SGGS. Guru Gobind Ji described the SGGS as the “King of Kings, Sun of suns” and as “God of Gods and above and beyond Praise” in the Jaapji Sahib in the Dasam Granth.
It is a reverential work containing 39 chapters across 1430 Angs (pages) with 5864 verses and 31 Raags (music melody with a relationship to human moods). It contains 937 hymns of 36 Hindu saints, Muslim Sufis and bards. These include the Sufi saints Baba Farid (134), and Bhikhan (2) and Bhakti saint Namdev (61), Kabeer (292) (also a Sufi).
Sikhs are not supposed to have anything against any religion, only against injustice and religious persecution. The Gurus lives set this example.
