Chapter 19 mentions Sai Baba served his guru for twelve years. Does the book explain what happened after those twelve years, maybe in later chapters?

The account in Chapter 19 details that Sai Baba stayed at his Guru's feet for twelve years, during which time he was raised from a child to an adult and was well cared for with no shortage of food or clothing. He describes a relationship of immense love and devotion, where he would constantly contemplate his Guru's face. The text notes that his Guru always protected him and expected nothing more than this intense devotion, along with faith and patience. While Chapter 19 provides this specific detail about the twelve-year period of service, the given excerpts do not contain any information about what happened afterward or what might be described in subsequent chapters of the book.
