What are the qualities of a true devotee, and what behaviors are criticized in Chapter 49 of the Sai Satcharitra?

According to Chapter 49 of the Sai Satcharitra, the hallmark of a true devotee is a complete lack of ego and pride in one's physical body. The text explicitly 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.' Conversely, the chapter criticizes those who possess an arrogance of knowledge, a pride of superiority, and are filled with hypocrisy. It also describes those who fail to sing the praises of their Guru with love as the 'personification of dull-wittedness.'
