According to Chapter 40, what is the nature of the relationship between a Sadguru and a devotee, and what is required from the devotee?

Chapter 40 explains that the relationship between a Sadguru and a devotee is one of profound merging and non-duality. When a devotee seeks 'exclusive refuge' in the Sadguru with true devotion, the Guru grants them His own divine nature. This is beautifully illustrated with the analogy of a river meeting the ocean; though they have different names, they are essentially one, and all difference is lost when they unite. The chapter further describes Sai's compassion as being like that of a 'compassionate mother to her infant,' emphasizing that He comes running to His devotees wherever they may be, highlighting the deep, protective, and loving bond that is formed through sincere faith.
