How does Sai Baba's teaching redefine death to help devotees overcome their fear of it?

According to the teachings in Chapter 43, death is redefined not as an end, but as the natural separation of the body and senses. For the wise, death is seen as a state of happiness for the body, while life is merely a modification of it. The text posits that birth and death are false imaginations, and for enlightened beings like Sai Baba, who is described as the complete Supreme Brahman, they are irrelevant. For those who have spiritually 'killed death' and placed their feet on the head of Time, there is no fear. Death is described as being like dust before such a person, helping devotees understand that it is not an event to be feared but a transition of form.
