The text states that for Amir's rheumatism, 'Baba's medicine was only His word.' What does this imply about Baba's healing methods?

This statement from Chapter 22 reveals a core aspect of Sai Baba's healing philosophy. For Amir Shakkar's rheumatism, the 'medicine' was not a physical substance but the divine command to stay in the inhospitable Chavadi. Baba's firm words were that Amir should not worry about the wind, rain, or dampness. The cure was embedded in an act of complete faith and surrender. By accepting Baba's word as the ultimate remedy and enduring the hardship for nine months, Amir's healing was tied to his internal faith rather than external comfort, showing that obedience to the Guru's word was the true medicine.
