If Sai Baba left his body, how does he continue to help and interact with his devotees?

Chapter 43 explains that Sai Baba's departure from his physical body was not an end but a transition into an unmanifest state. It states that he burned his body in the fire of Yoga and merged himself into the unmanifest, but importantly, he 'stayed in the hearts of the devotees.' His presence is not limited to a physical form. The text assures that even in this unmanifest state, he enjoys his true self and 'always keeps the devotees awake.' Furthermore, it is mentioned that his true form fills the entire moving and non-moving world. Devotees can still experience his presence and influence based on their own feelings and devotion. As Chapter 43 puts it, 'Whatever the feeling in one's mind, such is the experience even today,' proving his continued powerful existence.
