What is the purpose and benefit of reading the 'Sai Leela' or Satcharitra as described in Chapter 52?

According to Chapter 52, the book 'Sai Leela' was created to remember the experiences Sai Baba gave to His devotees while He was in the body. The text describes this Satcharitra as supremely holy, and reading this life story of the Guru is said to provide enlightenment for both this world and the next. This chapter also recommends a specific practice for devotees: after taking a holy bath in the Godavari and having darshan of the Samadhi, one should listen to this Satcharitra. The promised benefit is that the three types of afflictions will be calmed, and millions of sins will be dispelled by looking upon the book with love.
