What is Sai Baba's teaching on the nature of death, and how does this apply to his own passing?

According to Chapter 43, death is simply the separation of the body and senses, an event attached to birth and a natural state for the physical form. For an enlightened being like Sai Baba, who is a mass of bliss and the Supreme Brahman, the concepts of birth and death are illusory; the text states that death is like dust before him. His departure from the body was not a typical death but a conscious act—a merging into his unmanifest state through the fire of Yoga, undertaken for the sake of his devotees' salvation. His body is described as an adjunct, and he continues to exist in his true form, filling the entire world.
