There was however one shopkeeper, Mula, who wrote out for him on a piece of paper: “Death is the truth: living falsehood.” Mula`s curiosity led him to follow Mardana. He fell contentment in the Guru`s presence and became a disciple. He accompanied the Guru on part of his travels before he bade him to return and rejoin his family.
