If Sai Baba has left his physical form, how does he continue to help and protect his devotees?

According to the teachings in Chapter 43, Sai Baba's departure from his body was not an abandonment but a change in form. He 'merged himself into the unmanifest' but purposefully 'stayed in the hearts of the devotees.' The text emphasizes that even after transcending the material state, he 'always keeps the devotees awake.' By merely remembering his name, the fear of birth and death is removed. His influence is proven by the fact that devotees still experience his presence based on their feelings and devotion. In his true, powerful form, he fills the entire moving and non-moving world to protect his devotees' cause.
