How does the author of the preface compare the works of Annasaheb Dabholkar and Dasganu Maharaj regarding their content and style in writing about Sai Baba?

The preface provides a nuanced comparison between the biographical works of Annasaheb Dabholkar and Dasganu Maharaj. According to Chapter 0, both wrote about Sai Baba, but with significant differences. Dabholkar's 'Shri Sai Satcharita' is presented as a comprehensive, detailed work published over six years. In contrast, Dasganu Maharaj's two biographies, found within his larger poetic works 'Bhaktalilamrut' and 'Bhaktisaramrut,' are described as 'very short,' though still excellent and graceful. While the stories they relate about Baba are largely the same, a key stylistic difference is noted: Dasganu Maharaj beautifully depicted the 'pitiable state of our country and its causes,' a socio-political dimension that 'Shri Annasaheb did not involve himself in at all.'
