According to Chapter 40, what is the effect of Sai Baba's 'shaktipat' and how does one become receptive to His grace?

The teachings in Chapter 40 describe 'shaktipat' as a transmission of spiritual energy that occurs when Shri Sai Samarth places his hand upon a devotee's head. The immediate effect of this act is making the unattainable attainable by destroying the sense of duality. To receive this grace, the chapter indicates that a person must seek exclusive refuge in the Sadguru with sincere devotion. When a devotee offers a full prostration with this mindset, Sai embraces them, effectively merging them with His own Guru-nature, much like a river merges with the ocean.
