How does Sai Baba describe his own nature and his relationship with his devotees?

In Chapter 19, Sai Baba explains that his true nature is all-pervading and not limited to his physical body. He states, "I am pervaded in light and sky; I am not limited to one place," clarifying that he took a physical form of "three and a half cubits" to help devotees overcome their doubts. He describes an inseparable bond with those who worship him with an undivided and desireless heart, saying they are his "very self, without any sense of duality." To illustrate this unity, he uses powerful analogies: "Can jaggery remain separate from its sweetness? Can the ocean be separate from its waves? Can the eye remain without light? So is the innocent devotee without me." This shows that the true devotee becomes one with him.
