The text mentions that saints are the 'Agastya for the ocean of worldly existence.' Can you elaborate on what Chapter 12 means by this metaphor?

Chapter 12 uses a powerful metaphor to describe the function of saints. When it refers to them as the 'Agastya for the ocean of worldly existence,' it draws a parallel to the ancient sage Agastya, who is famed for drinking the entire ocean. In the same way, saints possess the spiritual power to absorb and nullify the vast, overwhelming ocean of worldly troubles and cycles (samsara) for their devotees. This chapter also complements this by calling them the 'sun for the darkness of ignorance,' highlighting their role in dispelling confusion and illuminating the spiritual path for followers, ultimately helping them transcend worldly existence.
