One day while Guru Nanak was walking in his village, he saw a saint sitting in meditation. He saw that the saint did a lot of meditation, but he had no food to eat. Guru Nanak decided to help this saint, so he gave the saint a brass jug that he could use for carrying water. He also realized that the saint would need money for food, so he gave the saint a gold ring that his parents had bought him. He told the saint, "Here, take this gold ring. You can sell it for money and then use that money to buy food." 

     When Mehta Kalu found out about this, he got mad. He started to shout at Guru Nanak. When Rai Bular found out that Mehta Kalu was yelling at his son again, he called him to his house. When Rai Bular met Mehta Kalu, he said, "You do not seem to understand how great your son is. His actions are always upsetting you. I suggest that you send him away to your daughter in Sultanpur (sulqwnpur), that way he will be away from you and he can find work there." 

      Rai Bular suggested this, because Guru Nanak's sister, Bibi Nanaki was living in Sultanpur. Bibi Nanaki had married Jai Ram (jY rwm), a minister who worked for Nawab Daulat Khan (nvwb dOlq ^wn), the ruler of Sultanpur. He thought that maybe Jai Ram could help find a good job for Guru Nanak there. 

      Mehta Kalu also agreed with this idea, he thought that maybe his son would start to work if he moved to another town. So Mehta Kalu asked his son if he would go and live with his sister. Guru Nanak agreed to move to Sultanpur. 

      Guru Nanak started to work as a store-keeper for Nawab Daulat Khan’s modhi khana.A modi khana is a store that belongs to the government, it carry’s groceries like sugar, flour, and rice. Instead of paying taxes, farmers would give a percentage of what they grew on their farms to the government. For example, if a farmer grew corn, he would give a percentage of that corn to the modi khana. When somebody bought something from the modi khana, it was weighed on a weight scale. On one side of the scale you would put the supply and on the other side you would put rocks to weigh the supplies. 

      One day Guru Nanak started to weigh some grain for some customers. He started to count the grain, but once he counted to the number thirteen he stopped. The number thirteen in punjabi is tera (qyrw), this word also means to belong to someone. Once Guru Nanak reached the number thirteen, he went into a trance. Concentrating on God, he started to say tera tera tera (I belong to you) over and over again for a long time. While he was saying this, the count of the grain went off, and the measurement was not accurate. Many customers got more grain than they paid for. 

      Some people noticed that Guru Nanak was giving away extra grain for free, so they went and complained to Nawab Daulat Khan. The accounts of Guru Nanak were then checked. Munshi Jado Rai was given the job of checking all of the accounts and seeing if any money was missing from the modi khana. When he finished checking, he found that there was no money missing, instead there was actually an extra 135 rupees.   

      The extra money was given to Guru Nanak, who then gave it to the poor people.   

      Guru Nanak stayed and worked in the modi khana for almost 14 years.   

      Over this time, there were three separate complaints made about Guru Nanak stealing money. However, when the money was checked, there was always extra money in the accounts. All three times Guru Nanak was found innocent.  

     There is a temple built where Guru Nanak use to work. This temple is called Gurdwara hutt Saheb (gurduAwrw h`t swihb). The rocks Guru Nanak used to weigh the groceries with are still there also
