According to Sai Baba, what are the spiritual benefits of reading sacred texts like the Guru Charitra?

Based on the events described in Chapter 18, Sai Baba teaches that the devotional reading, or Parayana, of sacred books like the Guru Charitra yields profound spiritual benefits. He explicitly states that by reading this book, devotees become pure. Furthermore, Baba explains that undertaking such a reading leads to overall welfare, pleases God, and ultimately helps to break the bonds of worldly existence. This is exemplified when he orders Mr. Sathe to perform another reading, highlighting its importance for spiritual purification and liberation.
