What does Chapter 21 say about the prerequisites for benefiting from spiritual teachings and the company of Saints?

Chapter 21 of the Sai Satcharitra emphasizes that certain prerequisites are necessary to truly benefit from spiritual discourse and the presence of Saints. The chapter begins by stating that a speaker's words are in vain if the listener is not emotionally moved. More significantly, it posits that encountering Saints requires divine grace and good fortune. As the author states, "this company of Saints is not accessible to the unfortunate; It is easy only when God’s grace is present." He uses his own past failure to visit the Siddha Pir Maulana, despite being in close proximity, to prove that even if a Saint is near, a "sinful person cannot see Him" if luck and grace are absent.
