If the author believed silence is the best praise for a Sadguru, what motivated him to write the Satcharitra as explained in Chapter 49?

While the author acknowledges in Chapter 49 that "maintaining silence is the real praise of the Sadguru," he was driven to write by an irresistible compulsion stemming from Sai's grace. He explains that each quality of Sai makes him forget his resolve for silence. The primary motivation was the desire to share the bliss with others. He compares this to tasting a sweet delicacy and immediately thinking of the "circle of listeners," feeling that the joy doubles when shared. He states that the thought of bringing others to this spiritual feast took root in his soul. Ultimately, he clarifies that Sai Himself prompted him to start the Satcharita to tell His stories to devotees and for the author's own "self-interest" in serving his Guru.
