What spiritual lesson is conveyed through Baba's seemingly harsh instruction for Amir Shakkar to live in the dilapidated Chavadi?

The story of Amir Shakkar in Chapter 22 imparts a powerful lesson on the nature of faith and surrender to the Guru. Baba's instruction for a man with rheumatism to live in a damp, cold, and filthy place appears harsh, but it served to strengthen and demonstrate the power of absolute faith. Baba's words, "Wind, rain, or dampness, Whether the place is high, low, or deep—do not weigh them," were the real medicine. By accepting this difficult command as a 'Great Prasad' and having 'certain faith' internally, Amir's well-being was assured. The lesson is that a devotee's unwavering obedience to the Guru's word transcends and triumphs over adverse material circumstances.
