Can you explain the idea of Sai Baba being both formless (Nirguna) and having a form (Saguna) as mentioned in Chapter 30?

Chapter 30 of the Sai Satcharitra explains a profound theological concept regarding Sai Baba's nature. It states that in the beginning, He resides as the formless, attributeless divine principle known as 'Nirguni'. However, it is through the 'qualities of devotees' devotion' that this formless reality is drawn into a 'form with attributes,' or 'Saguni.' This means the devotee's love, faith, and devotion act as the catalyst that allows the abstract, formless divine to manifest in a tangible, relatable form that they can see, interact with, and worship. This highlights that the Saguna form of Sai is a compassionate response to the devotee's yearning.
