How does Sai Baba explain the concept of non-duality in the relationship between a teacher and student to address feelings of isolation?

In Chapter 27, Sai Baba addresses the feeling of isolation by explaining the principle of non-duality. It is taught that a 'raw Guru' and a 'raw disciple' are those who have not overcome the sense of being separate. However, a disciple made by a perfect Guru has no room for duality. The text describes that both the devotee and the Guru should be intent on non-dual worship. When they meet in this state of unity, it is more than a mere transaction; it is a complete merging where separation ceases to exist. This understanding of being 'one with each other' fundamentally dissolves the illusion of isolation.
