Why was Cholkar chosen to document Sai Baba's stories and what was the ultimate goal of this work?

The provided text does not identify 'Cholkar' as the person chosen to document the stories. In Chapter 2, Sai Baba gives permission to the author, Hemadpant, but emphasizes that the author is only a pretext. The ultimate purpose of recording these stories, as explained by Baba, was for them to be a 'resting place for the soul.' He stated that by hearing and contemplating the stories with faith, devotion would be born, ignorance destroyed, and listeners would attain self-experience and happiness. The final goal described in Chapter 2 is for the devotee to gain knowledge of their true form and for the 'unperceivable, formless, and dense Consciousness' to manifest.
