How did Sai Baba describe His own true form after telling the author to perform His service?

After directing the author towards His service, Sai Baba elaborated on His true nature to explain what 'worship' truly entails. As explained in Chapter 3, He distinguished between His perishable physical body and His true, imperishable form as the Brahman. Baba stated that He is omnipresent, filling all of existence in the form of the eightfold nature (Ashtadha-prakriti), a concept also found in the Gita. He declared, 'I alone am everywhere. I am filled in all ten directions,' emphasizing that every object, moving or unmoving, is a manifestation of His divine play.
