How is Sai Baba's nature described in Chapter 50, and why is he considered beyond comparison?

Chapter 50 presents Sai Baba as a being of profound and incomparable nature. It describes him as 'purely an embodiment of consciousness' and the 'Unmanifest itself' having taken form. The text highlights his desireless and compassionate character, noting he lovingly speaks his own life-story for the benefit of his devotees. Furthermore, Chapter 50 explains why he cannot be compared to even the grandest natural phenomena. Unlike the sun which eventually sets, or the moon which waxes and wanes, Sai is described as 'forever complete.' This illustrates that his divine nature is eternal, unchanging, and absolute.
