The texts mention Baba's grace is determined by various factors. Can you explain his method of granting grace, including the analogy of the doctor and jaggery?

Chapter 27 describes Sai Baba's method of granting grace as being flexible and surprising, tailored to the individual devotee. The method of grace is determined by factors such as the devotee's authority, mental disposition, service, and love. An analogy is used to explain this: just as a doctor might use a trick, giving a patient jaggery first to make them take their medicine, Baba would sometimes use casual joking and humor to fulfill a devotee's purpose. This illustrates that force doesn't work, and Baba would change the 'vehicle' or medium to achieve his goal, demonstrating his unique and compassionate way of bestowing grace.
