What's the difference between true devotion to Sai and just superficial worship, according to Chapter 45?

Chapter 45 makes a clear distinction between genuine and superficial devotion. True devotion to Sai is described as worship with all senses fully engaged. The text warns against the hypocrisy of merely looking at an idol with one's eyes while the mind and other senses are preoccupied with worldly desires. It gives examples like hearing Sai's praise while thinking about the taste of mangoes, or touching Sai's feet while still craving the comfort of a soft bed. According to this chapter, a true Sai-devotee is someone who cannot bear to be separated from Sai even for a moment and knows how to be detached from the world.
