Using the example of Laxmichand, explain how Sai Baba demonstrated his 'inner knowledge'.

Sai Baba's 'inner knowledge' refers to his omniscience and ability to know the unspoken thoughts and desires of his devotees. The story of Laxmichand in Chapter 28 provides two clear examples. First, Baba knew of Laxmichand's unexpressed desire for khaja and his physical hunger and back pain, stating, "Hunger has come, that's good. There should be medicine for back pain." Second, when Laxmichand privately thought that Baba's cough might be from an 'evil eye', Baba later verbalized this exact concern. The text notes, "Whatever was in Laxmichand's mind, that was clearly expressed in Baba's words." This demonstrated to Laxmichand that Baba resides in the hearts of all and knows their thoughts, a concept described as an 'echo without sound'.
