As Nanak grew and became a man he thought about God all of the time. He was a dreamer and was not interested in working.
One day his father gave him 20 Rupees and told him to go to the city, buy something and then re-sell it to make a profit. When he arrived in the city he saw some monks who looked pale and ill. They told Nanak they had not eaten for 3 days. Nanak bought food for the monks and took it back to them.
When his Father found out he was very angry, but Nanak told him that feeding the hungry was a better way to spend the money. Nanak’s sister could see how angry her father was and asked if Nanak could live with her and her husband instead. Nanak’s father agreed.
