The text mentions Amir's stay felt like 'imprisonment.' Can you elaborate on the duality of his experience in the Chavadi?

Chapter 22 highlights a profound duality in Amir Shakkar's experience. Externally, his situation was like a prison sentence. He was confined for nine months to a single, squalid location while suffering from rheumatism and was even forbidden from going to the Masjid. The text notes that his mind desired freedom and that the thought 'Enough of this prison!' arose in him. However, internally, this period was one of immense spiritual fortune. It is described as having 'firm companionship with Sai,' a rare benefit. Despite the harsh physical conditions, his internal faith was certain, leading to constant, effortless contact with Baba. This contrast demonstrates how external hardship, when endured with faith, can lead to profound internal and spiritual rewards.
