How does the preface describe the contributions of Shri Dasganu Maharaj to the biographical literature of Sai Baba?

The preface acknowledges Shri Dasganu Maharaj as a foremost modern poet who was worthy of Shri Sai Baba's grace. According to Chapter 0, he authored two biographies of Baba, though they are noted to be very short. The first is found in his work 'Bhaktalilamrut' (Chapters 31, 32, 33) and the second in 'Bhaktisaramrut' (Chapters 52, 53). While these biographies are described as 'undoubtedly excellent, heart-touching, and graceful' and suitable for study, their brevity is a key distinction. The stories are mostly the same as those in Shri Sai Satcharita, but Dasganu Maharaj also uniquely depicted the pitiable state of the country, a topic Annasaheb Dabholkar did not address.
