What is the role of a Sadguru like Sai Baba in liberating a devotee from worldly struggles?

The role of a Sadguru is portrayed as paramount for spiritual liberation. According to Chapter 47, the holy face of Shri Sai is an abode of supreme bliss, and seeing it for even a moment can destroy the sorrows of infinite births. A merciful glance from the Guru can immediately liberate a devotee from the bonds of Karma and provide the nourishment of self-bliss. The text uses a powerful metaphor, stating that in the light of the sun of Sai's grace, the "firefly of worldly existence" loses its luster and vanishes. This highlights the Guru's power to dissolve the complications of action and non-action for the devotee.
