Describe the incident involving Baba's cough and explain how it strengthened Laxmichand's faith.

Chapter 28 recounts an event that profoundly impacted Laxmichand's faith. During the Chavadi procession, Laxmichand saw Sai Baba coughing and had a private thought that it might be the effect of an evil eye. The following morning in the masjid, Baba remarked aloud, "Yesterday I had much coughing; is this the effect of an evil eye?" Hearing Baba repeat his own internal thought verbatim filled Laxmichand with wonder and solidified his belief in Baba's omniscience. This confirmation that Baba knew his innermost thoughts caused him to plead for Baba's continued grace, deepening his devotion immensely.
