Based on Chapter 49 of the Sai Satcharita, what are the essential qualities of a true devotee?

Chapter 49 of the Sai Satcharita outlines that the most crucial quality of a true devotee is a complete absence of ego and pride. The text states, "The one who is completely devoid of ego truly possesses 'Devotee-hood.'" Conversely, it criticizes those who have pride in their body, arrogance of knowledge, or a sense of superiority, calling them an "abode of hypocrisy." A true devotee's greatest treasure is love for the Guru's feet, and they find ultimate fulfillment in meditating on their Guru. As this chapter explains, those who fail to sing the Guru's fame with love are considered dull-witted, underscoring the importance of humble and loving devotion.
