According to Chapter 49 of the Sai Satcharitra, what qualities define a true devotee versus someone who is not?

Chapter 49 draws a clear distinction between a genuine devotee and one who is not. A true devotee is characterized by being "completely devoid of ego," as the text states that "he who has complete pride in his body does not deserve the title of 'Devotee.'" In contrast, those who are not true devotees are described as having the arrogance of knowledge, the pride of superiority, and being an "abode of hypocrisy." The chapter further criticizes those who, despite being able to, do not sing the fame of their Guru with love, labeling them the "personification of dull-wittedness."
