Chapter 12 presents saints as having a significant role. Can you elaborate on how they are described as guides for humanity, using metaphors from the text?

Chapter 12 profoundly illustrates the role of saints using powerful metaphors. It states that saints are like 'Agastya (who drank the ocean) for the ocean of worldly existence,' signifying their ability to help devotees overcome the vast struggles of life. Furthermore, they are described as 'the sun for the darkness of ignorance,' capable of dispelling confusion and bringing enlightenment. The text emphasizes their boundless compassion, noting that their hearts 'break into pieces with compassion, and love overflows for the distressed.' This chapter portrays saints as inseparable from the Supreme Soul, acting as accessible guides who spend their own merits to help devotees.
