What are Sai Baba's teachings regarding death and why it shouldn't be feared?

According to the teachings in Chapter 43, death is simply the natural separation of the body and senses, just as birth is their union. For those who are spiritually realized, like saints, the end of the physical body holds no sorrow or grief. They are described as being happy in the bliss of Brahman, and the delusion of Maya cannot touch them. A saint who has metaphorically turned the body to ashes even before it falls has no fear of death; it is like dust before them. Therefore, death is not seen as an end but as a natural characteristic of the body, which is merely a temporary vessel.
