If Sai Baba merged into the 'unmanifest' after leaving his body, how can he still be present for his devotees?

Chapter 43 explains that while Sai Baba merged into the unmanifest, he simultaneously "stayed in the hearts of the devotees." His departure was not an end but a transition to his true, all-pervading form. The text reassures followers that by simply remembering his name, all notions of birth and death vanish. It states that even in his unmanifest state, Baba "enjoys the state of his true self and always keeps the devotees awake." The consciousness that was firmly imprinted in the hearts of his devotees did not perish. Therefore, his ability to protect and guide is not diminished; in his true form, he fills the entire world, and devotees can experience his influence based on the faith in their own minds.
