Based on the introductory chapter, describe Sai Baba's early lifestyle and acts of service in Shirdi.

In his early days in Shirdi, Maharaj lived a life of extreme simplicity and selfless service. Chapter 0 details that he mostly resided in a dilapidated Masjid, where he would spend his nights. He was completely detached from worldly possessions and never took money for the medicines he gave to people. His compassion was not just passive; the text highlights that if he found a patient who was not being cared for properly, he would go and personally undertake their care himself. This hands-on nursing and free distribution of medicine illustrate a life dedicated entirely to the welfare of others, long before he became widely renowned.
