How does Chapter 40 describe Sai Baba's role in helping devotees overcome the sense of duality?

According to Chapter 40, Shri Sai Samarth is blessed because He helps devotees by explaining both worldly interests and supreme spiritual goals. A key aspect of this is His ability to destroy the sense of duality. The chapter states that by placing His hand upon a devotee's head, He performs shaktipat and 'makes the unattainable attainable by destroying the sense of duality.' It further elaborates that He dissolves the separate feelings of 'me' and 'you,' embracing those who seek exclusive refuge. This unification is compared to a river meeting the ocean, where no difference remains, illustrating the merging of the devotee's identity with the Guru's, as detailed in Chapter 40.
