How did Baba's treatment for Amir Shakkar's rheumatism work, considering the physical conditions were counterproductive?

This story from Chapter 22 demonstrates that Baba's methods operated on a level beyond physical medicine. The external conditions—dampness, wind, and cold—were contrary to what one would expect for curing rheumatism. Baba's 'medicine' was simply His word, and He gave Amir firm instructions not to worry about the conditions. The cure was contingent on Amir's internal faith. By accepting Baba's word as the ultimate remedy and staying happily despite the hardship, his certain faith worked the healing from within, even while he was forbidden from visiting the Masjid for nine months.
