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

Chapter 30 provides a beautiful explanation of Sai Baba's dual nature as both formless (Nirguni) and with form (Saguni). The chapter posits that in his original state, the divine resides as formless and without attributes. However, it is through the power of the devotees' own devotion and faith that this formless essence is drawn into a perceptible form with attributes. This transition from Nirguni to Saguni is presented not as a change in the divine itself, but as a response to the devotee's love, making the abstract Absolute accessible to them as the tangible figure of Sai Nath, the 'crest-jewel among saints.'
