Gurudwara Bir Baba Budha Sahib, also known as Bir Sahib, is where Baba Budha Ji spent most of his life. Baba Buddha, who lived for 125 years, was the first Granthi, blessed by the first Sikh Guru Guru Nanak Dev as a boy, and went on to anoint the five succeeding Gurus. The Gurudwara complex, situated in the village of Thatta 20 km south of Amritsar, was built by Baba Kharak Singh to Honor the great Baba Budha. On the way to the Gurudwara, tourists can see the rich green paddy and wheat fields of Punjab, giving them an essence of true rural Punjab. Inside the Gurudwara, the holy Guru Granth Sahib is placed on a canopied seat made of white marble. Devotees come to this Gurudwara to seek blessings from Baba Buddha in hopes of a child, as was the case with Guru Arjan Dev, the fifth Sikh Guru, who came to Baba Buddha in hopes of being blessed with a child.
Legend has it that Baba Buddha used to live in the jungle outside Amritsar, spending most of his time looking after 'Bir'. Guru Arjan Dev, who was childless for many years, along with his wife Ganga Devi went to seek Baba Buddha’s blessings, offering him many delicacies which he refused. Mata Ganga then prepared Missi roti and an onion and visited Baba again after which. Impressed with the hospitality of the couple, Baba Buddha Ji gave them his blessings, shortly after which they were blessed with Guru Hargobind Singh Ji. Baba Buddha is said to have guided Guru Hargobind to use ammunitions after his father Guru Arjan Singh was martyred by Mughal emperor Jahangir, transforming the Sikh community into a martial race. The Gurudwara, in honour of the meal prepared by Mata Ganga, still serves Missi roti and onion as Prashad. Near the Gurdwara in a separate compound, there is a two-storied residential block, the Guru Ka Langar and a large dining hall. Each Bikrami month devotees in large numbers attend the celebrations, making it the biggest function of the year at this historic site.
