What were the three main Wadas in Shirdi mentioned in the text, and what was their significance?

Chapter 4 describes the sequential construction of three important Wadas that served pilgrims in Shirdi. The first was Sathe's Wada, which was the original and main place for pilgrims. It's also noted that this Wada was built on a spot that was originally a garden created by Baba's own hands. Later, Dixit's Wada was built, providing more spacious and convenient lodging. Finally, the text mentions the grand mansion of Shrimant Buti, or Buti Wada. This structure became supremely important as it was where Baba's physical body ultimately came to rest, making the money spent on it a worthy cause.
