Mata Sundari continued to saty at Delhi when Guru Gobind Singh went to the south, Mata Sahib Kaur told the Guru that since she had taken a vow to remain at his feet she would accompany him. The Guru acceded to her request reluctantly. She was latest sent back to Delhi from Nanded. Both Mata Sundari and Mata Sahib Kaur stayed at Kucha Dilwali Singhan neat Ajmeri Gate. They were looked after well by Bhai Nand Lal and Kirpal Chand, maternal uncles of Guru Gobind Singh. When Guru Gobind Singh was about to leave, Mata Sundari requested him to permit her to adopt a child who resembled her son Ajit Sinhg. Guru Gobind Singh pondered over the matter and allowed her to adopt him but at the same time warned her that resemblance of faces could not make the one like the other. After some time Mata Sundari and Mata Sahib Kaur shifted to their own house specially built for the purpose and popularly known as Haveli Mata Sundari. Mata Sundari took great interest in politics and guided the destiny of the Sikhs. After the death of Guru Gobind Singh, the Sikhs used to gather in the Haveli of Mata Sundari. Festivals of Diwali and Baisakhi were celebrated here every year. Later Mata Sundari told the Sikhs to hold meeting at Hari Mandir, Amritsar. Ajit Singh, the adopted son of Mata Sundari, declared himself to be the eleventh Guru of the Sikhs. Mata Sundari reprimanded him and disowned him. Soon after this, Ajit Singh was implicated in the murder of a Muslim Fakir and was killed after being tied to the tail of an elephant and dragged through the streets of Delhi on 18 June, 1725. For two years, both the holy mothers shifted to Mathura and came back to Delhi when things settled down. When Mata Sundari returned from Mathura she stayed at Haveli Mata Sundari. Mata Sundari died in 1747 while Mata Sahib Kaur died after about two years. The samadhis of both the holy mothers are located in Bala Sahib Gurdwara. After the death of Mata Sahib Kaur, the weapons of Guru Gobind Singh, which were given to her earlier, were preserved by Bhai Jiwan Singh and later by his descendants in their house in the Chitli Kabar Mohalla of Naya Bazar. They are an arrow, a sword, two katars, small knives and a Khanda - double edged sword. These are the weapons of which Mata Sahib Kaur used to have a darshan before taking her food. Building was constructed during the Sikh rule. On the farther end of the hall is a marble-paved gallery. The carved weed beam of the gallery bears an inscription in Gurmukhi script in bold letters. A marble slab in the centre, surrounded by the sacred emblem of the Sikhs, is also inscribed. The Gurdwara is built in brick and lime mortar.
