How did Sai Baba interact with his devotees' unspoken thoughts and desires, based on the events in Chapter 28?

Chapter 28 demonstrates that Sai Baba interacted with his devotees' inner worlds in a direct and omniscient manner. With Laxmichand, Baba mirrored his unspoken thought about the 'evil eye' causing his cough, confirming his ability to dwell within the devotee's heart. With the lady from Berhampur, Baba initiated the interaction by planting a desire in her through a dream, asking for khichdi and thus 'binding' her and drawing her to Shirdi. Her subsequent determination to fulfill this desire, even to the point of pushing past the curtain during mealtime, shows how Baba's initial call could inspire powerful resolve, which He ultimately rewarded.
