How does Chapter 30 describe Sai Baba's nature, particularly the transition from formless to having a form?

Chapter 30 of the Sri Sai Satcharita poetically describes Sai Baba's divine nature. It explains that in the beginning, He resides as the formless (Nirguni). However, it is through the compelling qualities of His devotees' devotion that He is drawn from the formless into a tangible form with attributes (Saguni). The text refers to Him as the "crest-jewel among saints," emphasizing that the devotee's faith plays a crucial role in the manifestation of the divine, making the abstract accessible and personal.
