Based on Chapter 30, what is the dynamic between Sai Baba's formless (Nirguni) and with-form (Saguni) aspects?

Chapter 30 explains a profound theological concept regarding Sai Baba's nature. It states that in the beginning, Sai resides as the formless, or 'Nirguni.' However, it is through the 'qualities of devotees' devotion' that He is drawn from the formless into a form with attributes, or 'Saguni.' This teaching, as presented in Chapter 30, suggests that the manifest, physical form of the Guru is a compassionate response to the devotee's need for a tangible focus for their love and faith. The formless takes a form out of mercy for those who seek a personal connection.
