How did Sai Baba explain his true nature beyond his physical body?

Sai Baba provided a deep explanation of his true self, distinguishing it from his physical form. He stated in Chapter 3 that 'Sai's body is perishable; the Brahman is imperishable and worthy of worship.' He elaborated that his real essence is the all-pervading Brahman, which manifests as the 'eightfold nature' (Ashtadha-prakriti) in everything, both moving and unmoving. He explained that everything in the universe with a name or form is a part of his play and that there is no object different from the Self. He confirmed his omnipresence by stating, 'I am filled in all ten directions,' urging devotees to see him everywhere and in everything.
