Mata Sahib Kaur Ji was born on November 1, 1681 in Village Rohtas, District Jhelum, Punjab (now in Pakistan). Her parents were Mata Jasdevi Ji and Bhai Rama Ji. Before Amrit, Mata Sahib Kaur Ji was called Mata Sahib Devan Ji.
It was the influence of her father that lead Mata Sahib Devan Ji to devote her life to the Guru. In addition to that, Mata Sahib Devan Ji’s father wished his daughter to marry Guru Gobind Singh Ji, however Guru Gobind Singh Ji was already married to Mata Sundari Ji. Thus, Mata Sahib Kaur Ji’s father asked the Guru permission so her daughter can stay with Guru Ji’s family at Sri Anandpur Sahib and devote here life to simran (recollection) and sewa (selfless service), Guru Sahib Ji agreed.
Since Mata Sahib Kaur Ji did not marry and had no children, Guru Sahib promised Mata Sahib Kaur Ji that she will become the great mother to thousands.
Mata Sahib Kaur Ji accompanied Guru Gobind Singh Ji throughout his life, even during battles, serving and guiding him in every possible way.
On Vaisakhi 1699, during the first Amrit Sanchaar at Sri Anandpur Sahib, it is said that Mata Sahib Kaur ji participated in the sewa of Amrit Sanchaar by adding Pataasey (sugar) to the Amrit. There she received the honour as eternal mother of the Khalsa Panth.
Then Mata Sahib Kaur Ji guided the Khalsa Panth through several periods of crisis, issuing eight orders in the name of the Khalsa.
It was Mata Sahib Kaur Ji, to whom, Guru Gobind Singh Ji handed the five weapons of Guru Hargobind Singh Ji (sixth Guru) for safekeeping, The weapons today are displayed at Gurdwara Rakab Ganj Sahib in Delhi.
Afterwards, Mata Sahib Kaur Ji stayed with Mata Sundari Ji in Delhi and lived a life of simran (recollection) and sewa (selfless service). Mata Sahib Kaur Ji passed away at the age of 66 in 1747 and was cremated at Gurdwara Bala Sahib in Delhi.
Today, all Sikhs who take Amrit consider Mata Sahib Kaur Ji as their spiritual mother, and Guru Gobind Singh Ji as their spiritual father.
