Why does the author of the Satcharitra say that silence is the best way to praise the Sadguru, but then go on to write the book anyway?

In Chapter 49, the author initially feels that silence is the most appropriate praise for the Sadguru, as even the Vedas and Puranas grew weary trying to describe His glory. However, he explains that the compelling qualities of Sai make him forget this resolution to remain quiet. He feels an urge to share the bliss with others, comparing it to bringing friends to a feast so the joy doubles. Ultimately, the author reveals that Sai Baba Himself is the driving force behind the writing. He states that if he tries to sit quietly, an unexpected story manifests, compelling him to write, and that Sai gives him remembrance at the right time. Therefore, he writes not of his own accord, but because Sai prompted him to start the Satcharita for the benefit of all devotees.
