How does Sai Baba decide to grant grace to his devotees?

According to the narrative in Chapter 27, Sai Baba's method for granting grace is not uniform but is wonderfully tailored to the individual. The text explains that the method is determined by factors such as the devotee's authority, mental disposition, service, and love. Baba's approach is likened to a doctor who understands the patient's condition. Just as a skilled doctor might use a trick, like offering sweet jaggery before bitter medicine to a resistant patient, Baba would sometimes use humor, jokes, or indirect means to fulfill a devotee's purpose and make them happy and prosperous. His grace could be granted unexpectedly, when it was not in anyone's thought.
