Discuss the concept of Baba's 'inner knowledge' as demonstrated through his interactions with Laxmichand in Chapter 28.

Chapter 28 powerfully illustrates Sai Baba's 'inner knowledge' or omniscience through his interactions with the devotee Laxmichand. This divine faculty is shown not as a vague intuition but as a precise perception of another's mind and body. For instance, Baba knew of Laxmichand's specific craving for khaja, his physical hunger, and his back pain, addressing them directly. The text describes this as an "Echo without sound." More profoundly, when Laxmichand had a private thought that Baba's cough might be from an "evil eye," Baba voiced that exact same speculation the next day. This demonstrated to Laxmichand that Baba "dwells in everyone's heart," perceiving thoughts as clearly as spoken words.
