Describe the second instance mentioned in the text where Baba demonstrated knowledge of Laxmichand's private thoughts, this time concerning a cough.

Chapter 28 recounts a later event where Baba's omniscience was again revealed to Laxmichand. During a Chavadi procession, Baba developed a cough. Seeing this, Laxmichand had a purely mental thought, wondering if the cough was due to someone's evil eye affecting Baba. The very next morning, when Laxmichand visited the masjid, Baba spoke in a similar manner, echoing the private thought that had only existed in Laxmichand's mind, once again proving his inconceivable inner knowledge.
