How does the scripture describe the ideal relationship between a Guru and a devotee, particularly regarding the concept of separation?

The text describes a profound unity between a Guru and a devotee, suggesting they are fundamentally inseparable. Chapter 27 explains that a Guru and devotee are "unique parts of one whole," and any attempt to forcefully separate them is futile. The scripture posits that if one believes the Guru is in one village and the disciple in another, both are considered superficial or "raw." The ideal state is one of non-duality, where there is no separation at all because they are "not two at all." This eternal oneness is so complete that one cannot remain without the other, making the physical act of a devotee placing their head on the Guru's feet just a "gross ritual" compared to this deep, internal unity.
