What is the Satcharita's philosophical perspective on birth and death, particularly in relation to Sai Baba?

According to the Satcharita, birth is defined as the union of the body and senses, while death is their separation. However, for an enlightened being like Sai Baba, these concepts are considered false imaginations. Chapter 43 explains that saints who incarnate by their own will for the welfare of devotees are not touched by birth and death. The text states that death is a characteristic of the soul's nature, and for one who has spiritually 'turned the body to ashes' even before physical passing, death holds no fear and is like dust. Sai Baba is described as the complete Supreme Brahman, for whom the consciousness of the body is an illusion, making the conventional ideas of birth and death inapplicable.
