Can you explain the concepts of 'Nirguni' and 'Saguni' as they are specifically applied to Sai Baba in Chapter 30?

In the theological context of Chapter 30, 'Nirguni' and 'Saguni' describe two aspects of Sai Baba's divine nature. 'Nirguni' refers to his primary state as the formless, attributeless, and unmanifested absolute reality. The chapter states, 'In the beginning, You reside as the formless (Nirguni).' 'Saguni,' on the other hand, refers to the divine with form and attributes. The text explains that it is 'through the qualities of devotees' devotion' that Baba draws the formless Nirguni into the Saguni form. This means his perceivable, human form is a manifestation of his grace, prompted by the love and need of his followers for a tangible focus for their devotion.
