Based on the introductory verses of Chapter 47, what are some of the divine powers attributed to Shri Sai's gaze and presence?

The beginning of Chapter 47 describes Shri Sai's divine attributes in powerful, poetic terms. According to these verses, simply seeing his holy face, which is called an "abode of supreme bliss," can destroy the sorrows of countless past lives. Furthermore, his "merciful glance" is said to be potent enough to immediately liberate a person from the bonds of Karma. The text in Chapter 47 also explains that in the light of his grace, the trivialities of worldly existence lose their luster and significance. This power is so profound that even the holy Ganges river is metaphorically depicted as desiring the dust from saints' feet, like Sai's, to purify itself.
