According to the source, on what basis did Sai Baba decide how to grant grace and instruction to his followers?

According to Chapter 27, Sai Baba's method for granting grace was highly personalized and not based on a single, rigid rule. The path of instruction was chosen based on the recipient's capacity and readiness. The text explicitly states that the method of grace is determined by factors such as the devotee's 'authority, mental disposition, service, and the devotee's love.' This is compared to a doctor who knows the correct diagnosis and medicine for a patient. Baba's acts were often surprising, and he might fulfill a devotee's purpose through casual joking and humor when least expected. This individualized approach ensured that his teachings and blessings were most effective for each person's unique spiritual journey.
