Sri Guru Nanak Dev Ji then proceeded to Bodh Gaya, where in those days, a Buddhist monk named Devgriha was the chief propagator of Buddhism. However, over the centuries, the influence of Buddhism had almost disappeared there, and instead, the Madhvacharya sect and Vaishnavism had gained significant influence.

Monk Devgriha attended Guru Ji’s congregations daily to listen to his sermons. He was so deeply influenced by Guru Ji that he became a devoted follower. Guru Ji established a dharamshala (religious rest house) in Gaya for the congregation, appointing Devgriha as the chief preacher. Devgriha followed Guru Ji’s command, got married, and adopted the grihastha ashram (householder's life).

From there, Guru Nanak Dev Ji traveled to Nalanda and Rajgir, which are located a short distance from Gaya. At that time, Rajgir had three sources of hot water but no source of cold water. Keeping in mind the needs of the local people, Guru Ji, along with the congregation, prayed to the Almighty for a cold water spring. As a result of their prayers, fresh, cool water became available in the town.

In the nearby town of Rajauli, a Sufi dervish named Kahlon Shah resided. Upon hearing about Guru Ji's divine praises, he came to meet him in person. After exchanging thoughts and ideas, Kahlon Shah was so deeply inspired that he invited Guru Ji to his residence, which was also his mausoleum. He served Guru Ji for several days with great devotion.

To spread Guru Ji’s sermons among the common people, Kahlon Shah began organizing large gatherings, which led to the establishment of a congregation known as Badi Sangat (Great Congregation). Over time, the place of these gatherings came to be known as Pir Nanak Shah Ki Badi Sangat. Even today, a sacred fire (Dhuni) is kept continuously burning at the site where Guru Ji once visited.
