Can you explain the theological concept of Sai Baba being both 'Nirguni' and 'Saguni' as described in Chapter 30?

Chapter 30 presents a sophisticated theological concept about Sai Baba's divine nature. It states, "In the beginning, You reside as the formless (Nirguni)." This refers to the ultimate, unmanifest, and attribute-less nature of God. The chapter then explains the transition: "Then, through the qualities of devotees' devotion, You draw the formless into form with attributes (Saguni)." This means that the abstract, formless divine (Nirguni) condescends to take on a tangible, perceivable form with qualities (Saguni), like that of Sai Baba, purely as a response to the love and faith of the devotees. The devotee's devotion is the catalyst that makes the formless accessible in form.
