Based on the provided text, what are the qualities that define a true devotee versus someone who is not?

Chapter 49 draws a sharp contrast between a true devotee and one who is not. It posits that a person who has "complete pride in his body" does not deserve the title of "Devotee." Instead, true "Devotee-hood" belongs to the one who is "completely devoid of ego." The text strongly criticizes those who possess arrogance of knowledge and pride of superiority, labeling them as an "abode of hypocrisy." Furthermore, it describes those who fail to sing the fame of their Guru with love as the "personification of dull-wittedness," emphasizing that genuine devotion is rooted in humility and love for the Guru.
