As a devotee seeking spiritual union, what can I learn from Chapter 40 about achieving oneness with the Guru?

Chapter 40 offers deep insights for a devotee aspiring for spiritual union. It teaches that the first step is to seek exclusive refuge in the Sadguru with devotion and a full prostration. When this is done, Sai dissolves the feelings of 'me' and 'you,' destroying the sense of duality. The chapter uses the powerful analogy of a river meeting the ocean, where their different names and forms disappear, and they become one in essence. By surrendering completely, the Sadguru grants the devotee His own Guru-nature, making the unattainable attainable, as explained in this sacred text.
