How does Chapter 30 explain Sai Baba's divine nature, especially the idea of him being both formless and with form?

Chapter 30 of the Sri Sai Satcharita explains that Sai Baba's fundamental nature is formless, or Nirguna. However, it is through the power and qualities of his devotees' devotion that He is drawn into a form with attributes, becoming Saguni. This chapter beautifully illustrates that Sai, the 'crest-jewel among saints,' takes on a tangible form out of compassion for His followers. As stated in the early verses of Chapter 30, He resides in the beginning as the formless, but the devotion of His followers compels Him to manifest in a form they can perceive and connect with, thereby dispelling their fear of worldly existence.
