According to the teachings, what is the nature of true devotion to a Guru like Sai Baba?

True devotion to Sai, as detailed in Chapter 45, requires the engagement of all one's senses in worship. It is a state where the devotee is entirely focused on the Guru, not allowing the mind to be divided by worldly distractions. The text cautions against superficial worship, describing it as looking at an idol while the speech is locked, or hearing Sai's praise while the tongue is preoccupied with the taste of mangoes. A true devotee, who cannot bear to be separated from Sai for even a moment, understands how to be detached from the world, making their worship a holistic and sincere offering.
