What is the ultimate vow Sai Baba takes for his followers, and how does this act as a source of profound comfort?

Sai Baba's ultimate promise, which serves as the greatest consolation for a devotee, is his vow of their liberation. In Chapter 3, he states this commitment clearly: "He who surrenders solely to me and worships me with faith, Contemplating me and remembering me; his liberation is my vow." This solemn promise, or 'brid,' assures followers that their final spiritual goal is personally guaranteed by Baba himself. This removes the deepest existential anxieties about one's journey and fate, providing a foundation of eternal happiness and peace that comforts the soul in any circumstance.
