How did Sai Baba describe His true, all-pervading nature when he was explaining the right way to worship Him?

In Chapter 3, Sai Baba provides a deep explanation of His real form, distinguishing it from His perishable physical body. He states that He is the imperishable Brahman, filled on all sides in the form of the eightfold nature (Ashtadha-prakriti), a concept He noted was also explained to Arjuna in the Gita. Baba clarified, "Whatever has name, form, or shape, in the world of the moving and unmoving, I alone am playing as the eightfold nature." He further identified Himself as the one indicated by Om (Pranav) and asserted that there is no object in the universe different from the Self. This teaching emphasizes that true worship involves recognizing His omnipresence in all of creation.
