How did Sai Baba explain his omnipresence and true form beyond his physical body?

Sai Baba provided a profound explanation of his true nature, as recorded in Chapter 3. He stated that while his physical body is perishable, the essence worthy of worship is the imperishable Brahman. He described himself as being filled on all four sides in the form of the eightfold nature (Ashtadha-prakriti), a concept He noted was also explained to Arjuna in the Gita. Baba clarified that he is present in everything that has a name, form, or shape in the entire world of the moving and unmoving. He is the one indicated by the sacred Om (Pranav) and is filled within all objects and in all ten directions, leaving no place separate from the Self.
