Can you describe Amir Shakkar's experience in the Chavadi and how it transformed from a trial into a blessing?

Amir Shakkar's stay in the Chavadi began as a severe trial. Chapter 22 describes the wretched conditions of the place, noting it was old, damp, and full of pests, which caused Amir great misery, especially with his rheumatism. He was even forbidden from visiting the Masjid. However, he accepted Baba's firm words as his medicine and stayed. This difficult trial transformed into a profound blessing because the Chavadi's location granted him automatic and frequent visions of Baba without any effort. He saw Baba during the morning alms round and again in the evening. This constant proximity turned his 'imprisonment' into a rare and fortunate 'firm companionship with Sai'.
