What philosophical truth about the nature of Sai Baba is established at the very beginning of Chapter 28?

The very beginning of Chapter 28 establishes a fundamental philosophical truth about Sai Baba's nature, asserting His omnipresence. The chapter opens by stating that "Sai is not separate from anyone; Sai dwells in all beings." This concept is expanded upon with the powerful imagery that from the highest being, Brahma, down to the smallest ant and insect, He pervades all, everywhere. Further verses in Chapter 28 elaborate that He is complete in Shabda-Brahma (the divine word) and shows the signs of Para-Brahman (the Supreme Being), reinforcing the idea that He is the ultimate reality manifest in and encompassing all of creation.
