When Baba told Annasaheb to perform 'my service', what did he mean? How did he explain his true form beyond his physical body?

When Sai Baba instructed Annasaheb to perform His service, He was referring to a deeper spiritual practice than mere physical worship. As explained in Chapter 3, Baba distinguished between His perishable physical body and His true, imperishable nature as the Brahman. He revealed that He is omnipresent, pervading the universe in the form of the eightfold nature (Ashtadha-prakriti), which includes everything with a name or form. He stated, 'I alone am playing as the eightfold nature; this is a miracle of mine.' Therefore, 'His service' means to recognize this divine presence in all beings and things and to live with the understanding that the Self is everywhere, which ultimately dissolves all desires and the ego.
