Based on Chapter 45, what characteristics define a true 'Sai-devotee'?

As detailed in Chapter 45, being a true 'Sai-devotee' is a profound state that goes beyond simple acts of worship. A true devotee is described as someone who feels separated from Sai for even a moment as an unbearable state. They are defined by their ability to be detached from the world, as one cannot be attached to Sai's feet without this detachment. The chapter emphasizes that their devotion must be all-consuming, offered with all senses fully engaged. Furthermore, their love for the Guru should be singular and exclusive, mirroring the unwavering devotion of a chaste wife to her husband. Ultimately, a true devotee renounces the transient world to meditate on the Guru as the eternal reality.
