Chapter 12 uses several metaphors to describe saints. Can you explain the metaphors of 'Agastya' and 'the sun' as they apply to saints?

Chapter 12 of Sai Satcharitra uses powerful metaphors to illustrate the role of saints. The text describes them as 'the Agastya for the ocean of worldly existence.' This refers to the sage Agastya who drank the entire ocean, meaning saints can absorb and nullify the vast struggles and sorrows of worldly life for their devotees. Furthermore, the chapter states that saints are 'the sun for the darkness of ignorance,' signifying that their wisdom and guidance can completely dispel spiritual ignorance, just as the sun dispels night's darkness. These metaphors from Chapter 12 highlight the immense power of saints to save and enlighten humanity, showing them to be inseparable from the Supreme Soul.
