What were Bapusaheb Buti's specific worries about the mansion when Sai Baba fell seriously ill?

When Sai Baba became seriously ill and his end seemed near, Bapusaheb Buti grew very uneasy and was filled with regret about the mansion. As described in chapter 39, his primary fear was that Baba's feet would never touch the temple he was building. He lamented the lakhs of rupees that had been spent, only to face this major obstacle. Buti's heart was troubled as he questioned the very purpose of the mansion and the Murlidhar temple, thinking, "After Baba has left his body, what is the use of Murlidhar or the house?"
