How does the beginning of Chapter 30 explain Sai Baba's nature and his role as a saint?

According to the opening verses of Chapter 30 of the Sai Satcharitra, Sai Baba initially resides in a formless state, known as Nirguni. However, through the devotion of his followers, he is drawn into a form with attributes, or Saguni. The text describes this as a key aspect of his nature. Furthermore, it states that the task of uplifting devotees is an unavoidable and inescapable duty for saints like Sai, who is called the "Acharya (teacher) of the assembly of saints." His darshan, or sacred viewing, is said to dispel the devotees' fear of worldly existence.
