How did Baba advise one to perform his service and what did he say about his true nature?

In Chapter 3, Sai Baba outlines the path to true service and worship. He instructs the author to perform His service with devotion, promising that by doing so, "The God of Gods will have mercy, and an eternal treasure will be found." Baba then clarifies the nature of the worship itself by distinguishing between his perishable physical body and his true, imperishable form as the Brahman. He explains that his real nature is the "eightfold nature (Ashtadha-prakriti)," meaning he is omnipresent and fills the entire universe. Therefore, as described in Chapter 3, true service involves recognizing this omnipresence in all of creation, both moving and unmoving.
