What does Chapter 50 teach about the importance of Satsang and the prerequisites for obtaining it?

Chapter 50 emphasizes that the company of the righteous, or Satsang, is a great blessing that is not easily obtained. The text states that one does not get the vision of a Saint, which removes the three-fold afflictions, without being "rich in penance in previous lives." This suggests that the opportunity to be in the company of a saint is a fruit of past merits. The chapter further elaborates on the benefits, explaining that for those who desire liberation or their own true welfare, becoming an instrument of the Saints is the key. As Chapter 50 beautifully puts it, "Blessed, blessed is the company of the righteous... From it comes discrimination and detachment, and supreme peace for the true devotees."
