What is the primary message about the power of Sai's presence as described in the introduction of Chapter 47?

The introduction of Chapter 47 describes the profound power of Shri Sai's presence. It states that seeing his holy face, which is the abode of supreme bliss, can destroy the sorrows of infinite births in a single moment. Furthermore, his merciful glance is said to immediately liberate a person from the bonds of Karma, allowing devotees to attain self-bliss without delay. The chapter emphasizes that before his gaze, the complexities of actions and non-actions vanish, and the struggles of worldly existence lose their power, much like a firefly's light pales in the presence of the sun.
