What does the text say distinguishes true devotion from superficial worship?

According to chapter 45, true devotion to Sai must involve all of one's senses and a mind detached from worldly desires. The text criticizes superficial worship, describing it as merely looking at an idol with the eyes while the mind and other senses are preoccupied with worldly pleasures, such as the tongue tasting mangoes or the body desiring soft beds. A true Sai-devotee is described as someone who cannot bear to be separated from Sai for even a moment and who knows how to be detached from the world. If love for God is not sparked and the mind does not find detachment, the text considers it a great downfall, especially for those fortunate enough to be born during Sai's incarnation.
