What are the core teachings about Sai Baba's spiritual power and his connection with devotees as detailed in Chapter 40?

Chapter 40 of the Shri Sai Satcharitra explains that Shri Sai Samarth has the power to bridge worldly interests and supreme spiritual goals. When he places his hand on a devotee's head, he performs 'shaktipat,' a direct transmission of spiritual energy. The chapter teaches that he makes the unattainable attainable by destroying the sense of duality, dissolving the separation between 'me' and 'you.' For devotees who seek exclusive refuge in him with sincere devotion, Sai grants them His own Guru-nature, much like a river merges with the ocean, leaving no difference between them.
