How do devotees experience Sai Baba's presence now that he is no longer in a physical form?

Even after his Mahasamadhi, Sai Baba continues to manifest his presence to his followers in subtle and miraculous ways. Chapter 43 explains that he shows himself in a "hidden form," granting visions to some, experiences to most, and performing miracles for many. The key principle mentioned is that the experience is deeply personal and dependent on the individual's devotion: "As is one’s state of mind, so is the immediate experience." Therefore, he is described as being hidden from the faithless but clearly visible and present for his faithful devotees.
