Based on Chapter 40, what are some of the key powers and characteristics of Shri Sai Samarth?

According to Chapter 40, Shri Sai Samarth is a blessed figure who helps devotees with both worldly interests and supreme spiritual goals. A key characteristic is his ability to perform shaktipat, the transmission of spiritual energy, simply by placing His hand on a devotee's head. He makes the unattainable attainable by destroying the sense of duality, dissolving the feelings of "me" and "you." As Chapter 40 describes, He is the protector of the humble and supremely loving, and although He pervades the entire universe, He chose to reside in Shirdi for His devotees.
