What are some of the metaphors used in Chapter 12 to describe the nature and function of saints like Sai?

Chapter 12 of the Shri Sai Satcharitra employs several powerful metaphors to illustrate the profound nature of saints. It describes a saint's form as being like the sky, which expands and fills all places, a state experienced only by the virtuous and fortunate. To convey their power to redeem souls from worldly troubles, saints are called the 'Agastya for the ocean of worldly existence,' referencing the sage who drank the entire ocean. Furthermore, to highlight their role in dispelling spiritual darkness, they are compared to 'the sun for the darkness of ignorance.' These metaphors collectively depict saints as vast, compassionate beings who absorb worldly suffering and illuminate the path to spiritual truth.
