Based on the text, what can be understood about Sai Baba's personal demeanor and the ultimate purpose of his incarnation?

Chapter 0 portrays Sai Baba as having a profoundly gentle demeanor, supported by a description from Shri Eknath Maharaj about how he would rub the body gently for fear of harming living beings. This gentleness was an expression of his greater purpose. The text explicitly states that Maharaj's incarnation was solely for the salvation of people and that he did good for everyone without a doubt. His method involved a compassionate process of satisfying the worldly desires of his devotees before seamlessly guiding their minds toward ultimate spiritual welfare, fulfilling his mission.
