What is a 'Parayana' according to the context of Chapter 18, and what is its purpose?

In the context of Chapter 18, a 'Parayana' refers to a devotional, week-long reading of a sacred text, such as the Guru Charitra mentioned in the story of the devotee Sathe. The purpose of this practice is deeply spiritual. When Sathe completed his reading and Baba ordered him to do another, Baba himself explained its significance. He stated that completing a Parayana helps devotees become pure, ensures their welfare, pleases God, and serves as a method to break the bonds of worldly existence. Therefore, it is presented not just as a reading, but as a powerful spiritual discipline for attaining purity and liberation.
