What was the deeper purpose of Baba making Amir Shakkar, a man with rheumatism, stay in a damp and dilapidated building?

The narrative in Chapter 22 suggests the purpose was a profound test of faith and surrender. By placing a man with rheumatism in a damp, cold, and uncomfortable place, Baba created a situation where all external conditions were contrary to physical well-being. However, the text emphasizes that Baba's word itself was the 'medicine.' The true test for Amir was to accept this instruction without argument, which he did. His ability to stay there happily for nine months, driven by 'certain faith,' demonstrates that the trial was designed to strengthen his internal spiritual state over his external physical comfort, proving that absolute trust in the Guru's word transcends worldly logic and hardship.
