What specific details does the introduction provide about Kashiram Shimpi's devotion and service to Sai Baba?

Chapter 0 provides a detailed account of Kashiram Shimpi's profound devotion. It states he became a total devotee who served Maharaj excellently with his 'body, mind, and wealth.' Specifically, Kashiram once stitched and gifted Maharaj a green kafni and a green cap, although Maharaj usually wore white. Furthermore, Kashiram took a vow to provide Maharaj with chillum, tobacco, firewood for his Dhuni, and money if needed. His financial devotion was so complete that he would place his entire money bag before Maharaj, inviting him to take as much as he wished.
