The Guru eventually agreed to the marriage, but made it clear that his relationship with Mata Sahib Devan would be of a spiritual nature and not physical. During the battle of Anandpur Mata Sahib Kaur was split from the holy family of the tenth Guru during the siege of Fort Keshgarh where, along with Mata Sundari, she was escorted to safety to Sri Damdama Sahib by Bhai Sahib Bhai Mani Singh Shaheed. Mata Sahib Kaur accompanied Guru Gobind Singh to Delhi and then on to Nanded whilst Mata Sundari stayed back in Delhi.

Mata Sahib Kaur resided in Delhi with Mata Sundari and lived a life of Simran and Seva (selfless service) for the panth (nation). Mata Sahib Kaur died in 1747 at the age of 66 and was cremated at Gurdwara Bala Sahib, New Delhi.
