How does Chapter 30 describe Sai Baba's transformation from formless to having a form?

Chapter 30 of the Sri Sai Satcharita poetically explains that Sai Baba initially resides in a formless state, referred to as 'Nirguni'. However, it is through the power and qualities of his devotees' devotion that He is drawn into a form with attributes, becoming 'Saguni'. The text describes Him as the 'crest-jewel among saints' and an 'abode of mercy' (Karuṇālaya), whose darshan alone can dispel a devotee's fear of worldly existence. This illustrates that the tangible form of the Guru is a compassionate manifestation for the sake of the devotee.
