What does the book say about Sai's existence after his physical body was gone?

Chapter 45 teaches that although Sai's physical body and form went, His essence remained in the Unmanifest, just as He was. His presence was not diminished, and the stories or 'Leelas' that occurred after his body's passing are described as being infinite. The text presents this as a fundamental truth for devotees to understand. It implies that the Guru's existence transcends physical form, and therefore, devotion should be directed towards this ever-present, unmanifest consciousness rather than being limited to the memory of His physical incarnation.
