Chapter 30 mentions Sai moving from 'Nirguni' to 'Saguni'. What does this philosophical concept mean in the context of devotion to Sai Baba?

Chapter 30 presents a deep philosophical concept regarding Sai Baba's divine nature. It explains that in the beginning, Sai resides as "Nirguni," which means formless, without attributes, and beyond perception. However, the chapter clarifies that it is "through the qualities of devotees' devotion" that He is drawn from this formless state into "Saguni," a form with attributes that can be perceived and worshipped. This teaching, as found in Chapter 30, highlights the immense power of a devotee's love and faith. It suggests that the manifest form of the Guru is a compassionate response to the devotee's yearning, making the abstract Absolute accessible to the sincere seeker.
