If Baba has merged into the 'unmanifest', how can devotees still connect with him or feel his presence?

Even though Sai Baba left his physical body, Chapter 43 stresses that his connection with devotees is stronger than ever. The text explains that while he 'merged himself into the unmanifest,' he also 'stayed in the hearts of the devotees.' It assures followers that by simply remembering his name, all notions of birth and death vanish. Most importantly, it confirms his continued accessibility by stating, 'Whatever the feeling in one's mind, such is the experience even today.' This proves his influence remains active, as he fills the entire world in his true form and 'always keeps the devotees awake,' acting as their protector.
