The book mentions many saints. Can you tell me what Chapter 50 says about the life of Saint Kabir?

The provided excerpts from Chapter 50 do not mention Saint Kabir by name. Instead, this chapter focuses on the supreme nature of Sai and the importance of devotion to a Saint in general. The text explains that conventional goals like the four types of liberation are not desired, but rather that "steady devotion to Sai be firmly attached; this is our supreme attainment." As described in Chapter 50, the awakening of devotion to a Saint is what purifies the heart, leading to a "natural state" where the distinction between the self and others dissolves, a state for which the devotees pray.
