[W]hy is Chapter Four called “Understanding by Faith?” This refers to the mental attitude of accepting faith. Faith appears in an honest heart. Neither logic nor reason can awaken faith in us. Faith grows beyond reason when we encounter someone beyond our capacities, or when we unexpectedly touch something absolute in our lives or in the cosmos. In Chapter Three, the sutra maintains, “They will be able to follow this sutra only because they believe my words, not because of their own wisdom” (p. 80).
