How does Sai Baba describe the ultimate reality of Brahman and its relationship to the visible world?

Sai Baba explains that the ultimate reality, Brahman, is the single essence that pervades the entire universe, from the highest being, Brahma, down to a simple blade of grass. Chapter 14 describes Brahman as a mass of pure consciousness, where worldly attributes and the distinctions of name and form are erased. Though the undiscerning eye may see a world of separate objects and beings (duality), this is an error caused by ignorance. In truth, everything is Brahman 'pervading through and through.' The goal is to see this oneness and recognize, as stated in Chapter 14, 'there is no place empty without Me.'
