How does the text use the concept of avatars and the illusory nature of the world to explain why fear of death is unfounded?

Chapter 43 explains that great souls and avatars like Sai Baba incarnate by their own will with the sole desire for the welfare of devotees. For them, birth and death are false imaginations that cannot touch them. The text emphasizes that Sai is the complete Supreme Brahman, and due to the truth of Brahman, the world itself is considered an illusion. If the world and the body are illusory, then the consciousness of the body and its eventual demise hold no ultimate reality. Death for saints is likened to a solar eclipse, which is merely a 'defect of vision.' This philosophical perspective encourages devotees to see beyond the physical form and overcome the fear of its inevitable end.
