How does Chapter 30 describe Sai Baba's nature and his transition from being formless to having a form?

Chapter 30 of the Sri Sai Satcharita beautifully explains that Sai Baba initially resides in a formless state, referred to as 'Nirguni.' However, it is through the qualities of his devotees' deep devotion that he is drawn into a form with attributes, becoming 'Saguni.' This chapter portrays him as the crest-jewel among saints and an abode of mercy, or 'Karuṇālaya,' whose very presence dispels the fears of his followers. This transformation highlights that the devotee's faith and love are what manifest the divine in a perceivable form.
