The text mentions Sai Baba left his body. Does this mean he is truly gone?

According to the teachings in Chapter 43, the idea that Sai Baba is truly gone is a misunderstanding of his nature. He was a Yogi who could die at will and chose to burn his body in the fire of Yoga, merging into the unmanifest. He transcended the material state to remain in the hearts of his devotees. The text argues that for such a being, who is filled with consciousness, the body cannot be said to have perished. This beginningless and endless Sai will remain unbroken, as he is beyond the states of birth and death and has become one with Brahman.
