When she completed her elementary education, the Qauzi got her admitted in the school of Sain Mian Mir for higher eduction She was very influenced by the personality of Sain Mian Mir and became his great devotee Sain Mian Mir had great respect for the Sikh Gurus. So he used to tell her about the Sikh Gurus and their hymns Sain also told her about Guru Hargobind Sahib Ji. Sain Mian Mir had learnt by heart many, hymns of Gurus So he used to recite those in a very melodious voice. Kaulaan also crammed some hymns and was feeling very blissful by reciting those in her sweet voice.
One day Quazi heard these hymns. He was a fanatic Muslim. He considered the Sikh Gurus as infidels. So he could not tolerate that his daughter should sing the hymns of infidels He warned her daughter not to sing such hymns.One day she requested Sain Mian Mir that she wanted to have a glimpse of the Guru Hargobind Sahib Ji. Once when the Guru had gone to meet Sain Mian Mir. Kaulaan got auspicious opportunity to see the Divine face of the Gum She was so impressed that she considered herself the most fortunate woman of the world She was so mesmerized that she could not utter a single word from her mouth. For some time she stood there as a lifeless statue Sain Mian Mir informed the Guru about the love of the girl for the Sikh faith. He also told the Guru that she used to sing the hynms of Guru Nanak Dev Ji in a very sweet voice The Gum blessed her and said, “You are very fortunate, whoever sings the praises of God, attains the Supreme Bliss.”
One day Bibi Kaulaan became so emotional that she began to sing the Divine Hymns in a loud voice She forget that Quazi was present in the house. When Quazi heard her voice, he was so enraged that he took one stick and began to beat her ruthlessly. Her mother requested the Quazi and saved her. But lovers of God never care about such beatings She started to recite the hymns day and night. When Quazi found that she had become fearless he requested his colleagues and got a decree passed by Mohammdan Priests. According to Muslim law ordained in Quraan, she was sentenced to death. When her mother heard about it she sent her in the school of Sain Mian Mir She also told him about the death sentence. Sain Mian Mir knew well that Nawab Wazir Khan and King Jahangir were friends of Guru Hargobind Sahib, so he planned to despatch Bihi Kaulaan to Amritsar . He called for Shah Abdul Yaar and advised him to take away Kaulaan to Amritsar He also told him to handover Kaulaan to Guru Hargobind Sahib so that he might make arrangements for her safe residence.
He reached Amritsar early in the morning and through an attendant of the Guru, met the Guru Hargobind Sahib and told him all about Kaulaan The Guru assured him that Sain Ji should not worry, she would be accomodated properly. Next day the Guru alloted her a house near Harimandir Sahib.He also made arrangements for meals and clothes. A lady attendant was recruited to help her and to give her company There Bibi Kaulaan was free to recite the hymns of the Gurus according to her desire.
One day mother Kaulaan asked her maid servant that she wanted to see the residence of the Guru. The maid servant agreed and she took her to Guru’s Mahal There when she saw the loveIy children of the Guru, she was very pleased to play with them She spent the whole day with them. But when she returned to her house she became very sad. She was thinking again and again about the children of the Guru.
