The text says Sai's body is gone but He remains in the Unmanifest. How does this idea influence the concept of devotion presented?

The teaching in Chapter 45 that Sai remains in the Unmanifest even after His body has passed is fundamental to its concept of devotion. It implies that connection to the Guru is not limited to physical presence. True devotion is an internal state of being, not an external act tied to a physical form. The text argues that if one's mind does not find detachment from the world and spark love for God, despite having the fortune to be born during Sai's incarnation, it is a great downfall. This leads to the definition of true worship as a complete engagement of all senses, rather than just superficial actions. A true devotee, who understands Sai's unmanifest nature, is one who is detached from the world and cannot bear even a moment of separation in consciousness from Him.
