How did Sai Baba react when Shama told him about the plans for the mansion, and did he give any hints about its future?

When Shama presented Bapusaheb's plan, Sai Baba reacted joyfully, saying, "Very well! After the temple is complete, we too shall come to stay there." Chapter 39 details how Baba then looked toward the mansion and spoke sweet, prophetic words: "After the mansion is finished, we will use it for ourselves. There we shall talk and walk; there we shall all play together. We will embrace each other with love and enjoy a bounty of joy." This foreshadowed that he, not a Murlidhar idol, would ultimately inhabit the space.
