What qualities define a true devotee versus an unworthy one, according to the teachings in Chapter 49?

Chapter 49 provides a clear contrast between true and false devotion. It asserts that a true devotee is one who is completely devoid of ego, stating that this "Devotee-hood" cannot belong to someone who has complete pride in their body. The chapter criticizes those who possess the arrogance of knowledge and pride of superiority, labeling them as abodes of hypocrisy. Furthermore, it describes those who fail to sing the fame of their Guru with love as the "personification of dull-wittedness." Therefore, the key qualities of a true devotee are humility, egolessness, and a loving dedication to praising the Guru.
