According to Chapter 30, how is Sai Baba's nature described, particularly in relation to being formless and taking a form?

Chapter 30 of the Sai Satcharitra beautifully explains the dual nature of Sai Baba. Initially, he is described as residing in a formless state, referred to as "Nirguni." However, it is through the power and qualities of a devotee's love and devotion that this formless divine energy is drawn into a form with attributes, or "Saguni." This chapter highlights that it is the devotee's faith that brings the abstract, formless divine into a tangible, relatable form, making Sai Nath the "crest-jewel among saints" who responds to the love of his followers.
