Who is the 'Cloud of Grace' mentioned in the book?

The provided text from Chapter 50 does not explicitly name a specific person or deity as the 'Cloud of Grace.' Instead, it is used metaphorically in a plea. The author, Hemadpant, uses the phrase after describing the groundwork for devotion: 'The land is well-plowed, and the seed is buried within. But if you, the "Cloud of Grace," do not rain, will the crop be produced?' In this context, the 'Cloud of Grace' represents the divine intervention or grace, likely from Sai Baba himself, that is necessary for the seed of faith and the stories of the saints to sprout and yield the crop of spiritual merit and devotion within the listener's heart.
