After some time, the parents of the girl agreed to send their daughter with Bhai Gurdas. But he refused to take her along with him, stating that he had now renounced the worldly way of life. In his memory, his Smadh was constructed where a fair is held every year in March–April. People in large numbers attend the fair and offer Laddus and Gur (Jaggery) at Smadh.
