Analyze Sai Baba's pedagogical approach using the doctor-patient analogy from the source text.

Chapter 27 presents a sophisticated pedagogical approach used by Sai Baba, illustrated through the analogy of a doctor and a patient. In this metaphor, the devotee is the 'patient' who, not understanding what is best for them, insists on 'jaggery'—a sweet but ultimately harmful attachment or desire. Baba, the all-knowing 'doctor', understands the diagnosis and the proper 'medicine' (grace or instruction). Rather than using force, he employs a trick; he provides the jaggery first to make the medicine palatable, but skillfully changes the 'vehicle' of the medicine to nullify the jaggery's ill effects. This shows that Baba's method of instruction was not rigid but adapted to the recipient's capacity, using indirect means to achieve his ultimate purpose of healing and guiding the devotee.
