How is the Supreme Reality, or Brahman, defined at the beginning of Chapter 19?

The start of Chapter 19 provides a profound description of Sai as the Supreme Reality, or Brahman. He is defined as the object that resides in everything, from the smallest atom to the entire vast universe. The text emphasizes this all-encompassing nature by stating He is "subtler than the subtlest and greater than the greatest." The author then expresses a personal longing to give this formless Supreme Reality a tangible form, color, and shape to be perceived with physical eyes. This introduction in Chapter 19 frames Sai not just as a Guru, but as the ultimate goal where the senses and mind can find rest.
