Can you describe the origin of the name 'Sai Baba' as explained in the introduction?

The name 'Sai Baba' was bestowed upon Maharaj when he first entered the Khandoba temple in Shirdi. According to Chapter 0, a devotee of Khandoba named Mhalasapati was present in the temple. Upon seeing Maharaj, who was wearing a kafni, a cap, and a dhoti, Mhalasapati spontaneously greeted him with the words 'Aavo Sai Baba,' which means 'Come, Sai Baba.' From that moment on, Maharaj held onto that name. The text further clarifies that when his testimony was taken in a commission and he was asked his name, he replied, 'They call me Sai Baba,' indicating his acceptance of the name given by Mhalasapati.
