What qualities define a true devotee, and which traits are criticized, based on the teachings in Chapter 49?

Chapter 49 provides a clear distinction between a true devotee and one who is not. It teaches that a person who has "complete pride in his body" or the "arrogance of knowledge and the pride of superiority" does not deserve the title of "Devotee." True "Devotee-hood" is possessed by one who is completely devoid of ego. The chapter strongly criticizes those who are merely an "abode of hypocrisy" and those unfortunate, dull-witted individuals who do not sing the fame of their Guru with love. The central message conveyed in Chapter 49 is that humility and the surrender of ego are essential for genuine devotion, while pride and arrogance are significant obstacles.
