What transpired when Sai Baba commanded Das Ganu to organize a Name-week?

According to Chapter 4, Sai Baba, who loved the chanting of God's name, ordered Das Ganu to organize a Name-week, or Saptah. Das Ganu agreed but made a condition, stating that Lord Vitthal must appear as a result of the week-long chanting. In response, Sai Baba placed His hand on His chest and firmly promised Das Ganu, "Yes, yes, the form of Vitthal will appear! But the devotee must be full of faith." Baba emphasized that Shirdi itself was a holy city like Pandhari and one need not go elsewhere. The scripture confirms that Baba's promise was fulfilled, as it is said that at the end of the Saptah, Das Ganu received the blessed sight of Vitthal in Shirdi.
