Did Sai Baba really die? I'm confused about what it means when people say he left his body.

This is a profound question that Chapter 43 addresses directly. It explains that for a great Yogi like Sai Samarth, death as we understand it is not applicable. He is described as the 'complete Supreme Brahman' for whom birth and death are illusions. The text suggests that when his task for the devotees was complete, he did not simply perish but chose to merge himself into the unmanifest state, having burned his physical form in the 'fire of Yoga.' Chapter 43 emphasizes that he remains ever-present in the hearts of his devotees and continues to fill the entire world in his true form, making the concept of his body perishing something the author's mind cannot accept.
