Since Baba is no longer in his physical form, what is his current state and how does he continue to guide his followers?

The text explains that after leaving his body, Sai Baba's state is one of complete unity with the divine. Chapter 43 describes this as having 'merged himself into the unmanifest' and having 'become one with Brahman.' In this true form, he is omnipresent, filling the entire 'moving and non-moving world.' He continues to guide his followers by residing 'in the hearts of the devotees' and, as the text explicitly states, he 'always keeps the devotees awake.' His influence is proven to persist, and devotees can still receive his guidance and experience his presence, as the text notes, 'Whatever the feeling in one's mind, such is the experience even today.'
