The texts say saints are beyond death. How is the concept of death explained in relation to a being like Sai Baba?

Chapter 43 explains that for a perfected being like Sai Baba, death is not a source of sorrow or grief. Death is defined as the separation of the body and senses, while birth is their union. However, for saints who have 'killed death' and are free from the six-fold emotions, this process is a 'false imagination.' As the text states, Sai Samarth is a 'mass of bliss' and the complete Supreme Brahman, for whom birth and death do not exist. His physical passing is compared to a solar eclipse—a mere defect of vision for the observer, not a reality for the saint who is eternally in an unmanifest state.
