Chapter 30 talks about Sai moving from 'formless' to 'form with attributes'. What does this mean, and why does it happen?

Chapter 30 explains that Sai Baba initially resides in a formless, or 'Nirguni', state. However, driven by the qualities of his devotees' deep devotion, he is drawn into a form with attributes, or 'Saguni'. This transition from the abstract to the tangible is presented as an act of compassion for his followers. The text emphasizes that it is the devotees' faith and love that compel the formless divine to take a form they can perceive and interact with. As the chapter states, this is how Sai Nath, the crest-jewel among saints, manifests for the sake of those who worship him, making his divine presence accessible.
