Since Sai Baba's physical form is gone, how can a devotee still experience His presence and work towards liberation?

Chapter 45 explains that although Sai's physical form vanished, this was merely the passing of the body. The text emphasizes that Sai Himself is beyond birth and death, remaining present in the Unmanifest. He established His form in the hearts of devotees through meditation, which is one way to experience His presence. Furthermore, the Satcharitra itself is described as His 'literary form,' which provides remembrance at every step. The chapter assures devotees that by listening to these stories with a concentrated mind, they perform a holy act that brings a unique peace. Through these means, Sai continues to fulfill the worldly and spiritual goals of His devotees, proving His service never goes in vain.
