How did Sai Baba explain his true, divine nature beyond his physical form?

In Chapter 3, Sai Baba explains that his physical body is perishable, but his true self is the imperishable Brahman, which is worthy of worship. He describes himself as being omnipresent, filled everywhere in the form of the eightfold nature (Ashtadha-prakriti), a concept he noted was also explained to Arjuna in the Gita. He stated, "Whatever has name, form, or shape, in the world of the moving and unmoving, I alone am playing as the eightfold nature." Baba clarified that he is present in all ten directions and that when one truly understands this omnipresence and the essence of 'Who am I,' all desires dissolve, just as hail melts in the sun.
