How does faith at the feet of the Saints help a devotee, especially in the context of karma and rebirth mentioned in the chapter?

Chapter 48 explains that people are reborn to settle debts and experience the fruits of their karma, often with no memory of their past. In contrast, it notes that Saints like Sai 'never forget' and possess the ability to 'remove the calamities of their devotees.' The text concludes by stating that 'those devotees who place faith at the feet of the Saints attain success.' By connecting faith with the Saints' ability to intervene in the karmic cycle, Chapter 48 suggests that surrendering with faith is the key to overcoming the otherwise binding consequences of past actions and avoiding the difficult cycle of rebirth mentioned earlier.
