According to Chapter 27, what factors influenced how Sai Baba decided to grant grace to a particular devotee?

Chapter 27 explains that there was no single, rigid rule for how Sai Baba bestowed his grace; rather, his method was determined by a combination of factors specific to each person. The text states that the method of grace was decided according to the devotee's authority or capacity, their mental disposition, their record of service, and the depth of their love. This means Baba's wonderful acts were tailored to the individual. His grace could manifest unexpectedly, sometimes through casual joking and humor, to fulfill a devotee's purpose when it was least anticipated, demonstrating a highly personalized and insightful approach.
