According to Chapter 49, what qualities define a true devotee versus an undesirable one?

Chapter 49 draws a sharp contrast between a true devotee and one who is not. It states that a person who has complete pride in their body cannot be called a 'Devotee,' as true 'Devotee-hood' belongs to one who is completely devoid of ego. The chapter criticizes those with the 'arrogance of knowledge and the pride of superiority,' calling them an 'abode of hypocrisy.' Furthermore, it describes those who do not sing their Guru's fame with love as the 'personification of dull-wittedness,' emphasizing that humility and loving devotion are the essential qualities.
