How does Chapter 30 of the Sai Satcharitra describe Sai Baba's nature as both formless and having a form?

Chapter 30 explains that Sai Baba's fundamental nature is formless, or 'Nirguni.' However, it is through the devotion and love of his followers that he is drawn into a tangible form with attributes, known as 'Saguni.' As the text describes, "In the beginning, You reside as the formless (Nirguni). Then, through the qualities of devotees' devotion, You draw the formless into form with attributes (Saguni)." This transformation from the abstract to the manifest is presented as an act of compassion, undertaken by saints like Sai Baba for the specific purpose of uplifting their devotees. This concept, detailed in Chapter 30, highlights how a saint's form is a response to the devotee's need for a perceptible object of faith.
