How can I be sure my devotion is correct if the saint I follow isn't mentioned by name in the Satcharita?

The Satcharita provides profound reassurance by focusing on the devotee's state of mind rather than the specific object of devotion. Chapter 19 reveals the vital secret of the Bhagavad Gita: "'Those who think of Me with undivided attention'—...Govinda provides the well-being and security (Yogakshema) of those who are thus constantly united." Your sincerity and undivided attention are what truly matter. As the author experienced when he chose to chant Rama's name, if a "wave of good thoughts arises, one should certainly nurture it." By doing so, great satisfaction will be felt. Sai Baba supports all true devotion, confirming His grace is available to all who approach with a pure heart.
