Describe the incident involving Sai Baba's cough and how it affected Laxmichand's faith.

A pivotal moment in strengthening Laxmichand's faith is detailed in Chapter 28. During the Chavadi procession, Laxmichand observed Baba coughing and a private thought arose in his mind that an 'evil eye' might be the cause. The next morning in the masjid, Sai Baba vocalized this secret thought, asking Madhavrao, 'Yesterday I had much coughing; is this the effect of an evil eye?' For Laxmichand, hearing his own unexpressed thought from Baba's mouth was a profound wonder. It confirmed Baba's omniscience, causing him to plead with folded hands for continued grace and cementing his belief that Baba resides in the hearts of all.
