According to the text, what qualities define a true devotee versus someone who is not?

Based on the source text from Chapter 49, a true devotee is defined by their complete lack of ego. The text states that one who has "complete pride in his body does not deserve the title of 'Devotee,'" and that true "Devotee-hood" belongs to the one who is "completely devoid of ego." The chapter further criticizes those who possess an arrogance of knowledge, a pride of superiority, or are filled with hypocrisy, questioning their prestige. It also describes those who fail to sing the praises of their Guru with love as being the "personification of dull-wittedness."
