If Baba has merged into the unmanifest, how can devotees still experience His presence?

Even though Sai Baba merged into the unmanifest, Chapter 43 assures devotees that he remains ever-present and active. The text states that he 'stayed in the hearts of the devotees' and 'always keeps the devotees awake.' His presence is not limited to a physical form; in his true form, he 'fills the moving and non-moving world.' The scripture emphasizes that a devotee's experience is shaped by their own feeling, stating, 'Whatever the feeling in one's mind, such is the experience even today.' By simply remembering his name, the illusion of his absence is dispelled, proving his continued influence and protection.
