Gurudwara Doodh Wala Kuan Sahib is located near Gurudwara Nanak Matta Sahib. The Siddhas who inhabited this place possessed a large number of cows. Bhai Mardana expressed a desire for milk. Guru Ji told him to ask the yogis for some milk. The Siddhas refused to give him any milk and taunted him by telling him to get milk from his Guru. By virtue of his spiritual powers, Guru Sahib drew all the milk from the cows of the yogis and stored it in a well. It is said that the water of this well tasted like milk. Since that time, this well is called the Doodh Wala Khu, or the Well of Milk. Along with the historic well, the Gurudwara is constructed thereafter known as Gurudwara Doodh Wala Kuan.
It is also said that any person whoever takes a holy bath with the water of this well and then prays to Guru Ji (God), he / she gets sufficient milk and son in the family.
