How does the source explain the concept of a saint's 'death' using Sai Baba as an example?

The source explains that a saint's departure is not a death in the conventional sense. Chapter 43 clarifies that saints are the personification of Brahman and appear on Earth for the purpose of helping others. When their task is complete, they do not perish but rather merge back into their true, unmanifest form. For a great soul like Sai Baba, who is described as a treasure of knowledge, the care for the body and its eventual fall are considered the same. Thus, while his physical departure caused a mountain of sorrow, he himself simply transitioned, becoming one with Brahman and transcending his material state.
