What kind of treatment did Baba give for Amir's rheumatism? Was it a physical medicine?

The source material in Chapter 22 indicates that Sai Baba's medicine for Amir Shakkar's rheumatism was simply 'His word.' There is no mention of physical remedies or herbs. Baba's firm instruction was to stay in the damp and windy Chavadi and not to question the conditions. The text states, 'Accepting His word as medicine, he stayed there happily.' The cure was rooted in complete faith and obedience to Baba's command, even when external conditions were contrary. The healing was based on internal faith and 'certain faith' rather than any external treatment.
