Mai Bhago was was a descendant of Pero Shah, the younger brother of Bhai Launga a Dhillon Jatt who had converted a Sikh during the time of Guru Arjan. Born at her ancestral village of Jhabal in present-day Amritsar district of the Punjab, she was married to Nidhan Singh Varaich of Patti. A staunch Sikh by birth and upbringing.
Mughals and hilly chiefs had surrounded Anandpur and were demanding it be evacuated. They called that any Sikh who says that “he/she is not anymore a Sikh of Guru Gobind” will be left untouched. A group of 40 Sikhs, led by Mahan Singh Brar told Guru Gobind Singh that they are not his Sikhs anymore.
Guru told them that they have to write it in a document that “they are not his Sikhs anymore” and sign it. All forty Sikhs signed this document Bedava and left Guru Gobind Singh. Mai Bhago was distressed to hear that some of the Sikhs of her neighbourhood who had gone to Anandpur to fight for Guru Gobind Singh had deserted him under adverse conditions.
Hearing her taunts, these Sikhs were ashamed at their deed. She rallied the deserters persuading Guru, then traveling across the Malva region.
